Rational Self-Assembly of Tricobalt Extended Metal Atom Chains and [MF6]2? Building Blocks into One-Dimensional Coordination Polymers

Following our recent work on the first crystallographically characterized coordination polymers based on tricobalt extended metal atom chains (EMACs), namely, [Co3(dpa)4MF6]¡¤2DMF [M = ZrIV (1), SnIV (2), and ReIV (3); Hdpa = 2,2?-dipyridylamine; DMF = N,N?-dimethylformamide], we have generalized our synthetic approach based on robust fluoride complexes to prepare new self-assembled one-dimensional (1D) polymers formed by [Co3(dpa)4]2+ and 5d [MF6]2? [M = IrIV (4) and OsIV (5)] building blocks. These 1D complexes are isostructural and crystallize in the P4/ncc space group such that the fourfold axis is coincident with the metal axes of the rigorously linear chains. Magnetic studies reveal ferromagnetic coupling between the S = 1/2 {Co3} and [MF6]2? units in 3 and 4, whereas the nonmagnetic [MF6]2? linkers of 1 and 5 mediate antiferromagnetic coupling between the {Co3} spins. For 2, no significant exchange coupling was observed. Spin-crossover behavior, which was observed for the parent [Co3(dpa)4Cl2] complex, was not detected for 1?5 up to 300 K. This work demonstrates that EMACs and [MF6]2? complexes can be considered as appealing building blocks for the design of new functional coordination networks.

Synthetic routes to homoleptic and heteroleptic ruthenium(II) complexes incorporating bidentate imine ligands

Ruthenium(II) complexes are finding applications in a variety of fields and, in particular, as photo-sensitisers in the conversion of solar energy into chemical or electrical energy where a major achievement has been the development of a dye sensitised solar cell (DSSC) by the Graetzel group. In order to optimise the performance of such devices there is a need to prepare complexes with tunable spectral and physico-chemical properties. Synthetic approaches have been developed which enable the rational synthesis of heteroleptic tris(diimine)ruthenium(II) complexes with the desired properties. In this review we focus on contributions made by our group which have led to the development of two approaches to such heteroleptic complexes both of which use [Ru(CO) 2Cl2]n polymer as a key precursor. These approaches differ in that one requires conversion of [Ru(L)(CO) 2(Cl)2] into a triflate complex, [Ru(L)(CO) 2(CF3SO3)2] followed by substitution of the triflate by a second diimine ligand (L1) to form [Ru(L)(L1)(CO)2]2+ and chemical decarbonylation in the presence of a further diimine ligand (L2) to [Ru(L)(L 1)(L2)]2+ while the other involves photodecarbonylation of [Ru(L)(CO)2(Cl)2] to produce [Ru(L)(CO)(Cl)2]2, which on sequential addition of two further diimine ligands finally yields [Ru(L)(L1)(L 2)]2+. These versatile methods, together with those developed by others, provide the synthetic tools needed to produce Ru(II) complexes with properties required for a particular application.

Four alkoxohexavanadate-based pd-polyoxovanadates as robust heterogeneous catalysts for oxidation of benzyl-alkanes

Four alkoxohexavanadate-based Pd-POVs [Pd(dpa)(acac)]2[V6O13(OMe)6] (1), [Pd(dpa)(acac)]2[V6O11(OMe)8] (2), [Pd(dpa)(acac)]2[V6O11(OMe)8]¡¤H2O (3), and [Pd(DMAP)2(acac)]2[V6O11(OMe)8]¡¤H2O (4) (POV = polyoxovanadate; dpa = 2,2?-dipyridine amine; DMAP = 4-dimethylaminopyridine; acac = acetylacetone anion) have been synthesized and fully characterized by single crystal X-ray diffraction and powder X-ray diffraction analyses, Fourier transform infrared spectroscopy, element analyses, and X-ray photoelectron spectroscopy. In 1-4, Pd complexes and hexavanadate anions are assembled through electrostatic interactions. Interestingly, the [V6O11(OMe)8]2- cores in 2 and 3 are a pair of isomers that can be isolated by controlling crystallization temperature. Moreover, to the best of our knowledge, the {V6} core in 3 represents a new octamethoxyhexavanadates cluster. It is notable that compounds 1-4 exhibit excellent heterogeneous catalytic performance in the oxidation of benzyl-alkanes with t-butylhydroperoxide as oxidant. Among them, the catalytic activity of 1 (conv. and selec. up to 99%, respectively) outperforms others and can be reused without losing its activity.

Synthesis, structure and spectral and redox properties of new mixed ligand monomeric and dimeric Ru(ii) complexes: Predominant formation of the “cis-alpha” diastereoisomer and unusual 3MC emission by dimeric complexes

The tetradentate ligands 1,8-bis(pyrid-2-yl)-3,6-dithiaoctane (pdto) and 1,8-bis(benzimidazol-2-yl)-3,6-dithiaoctane (bbdo) form the complexes Ru(pdto)(mu-Cl)2(ClO4)2 1 and Ru(bbdo)(mu-Cl)2(ClO4)2 2 respectively. The new di-mu-chloro dimers 1 and 2 undergo facile symmetrical bridge cleavage reactions with the diimine ligands 2,2?-bipyridine (bpy) and dipyridylamine (dpa) to form the six-coordinate complexes Ru(pdto)(bpy)(ClO 4)2 3, Ru(bbdo)(bpy)(ClO4)2 4, Ru(pdto)(dpa)(ClO4)2 5 and Ru(bbdo)(dpa)(ClO 4)2 6 and with the triimine ligand 2,2?:6,2?- terpyridine (terpy) to form the unusual seven-coordinate complexes Ru(pdto)(terpy)(ClO4)2 7 and Ru(bbdo)(terpy)(ClO 4)2 8. In 1 the dimeric cation Ru(pdto)(mu-Cl) 22+ is made up of two approximately octahedrally coordinated Ru(ii) centers bridged by two chloride ions, which constitute a common edge between the two Ru(ii) octahedra. Each ruthenium is coordinated also to two pyridine nitrogen and two thioether sulfur atoms of the tetradentate ligand. The ligand pdto is folded around Ru(ii) as a result of the cis-dichloro coordination, which corresponds to a “cis-alpha” configuration DeltaDelta/LambdaLambda (rac) diastereoisomer supporting the possibility of some attractive pi-stacking interactions between the parallel py rings at each ruthenium atom. The ruthenium atom in the complex cations 3a and 4 exhibit a distorted octahedral coordination geometry composed of two nitrogen atoms of the bpy and the two thioether sulfur and two py/bzim nitrogen atoms of the pdto/bbdo ligand, which is actually folded around Ru(ii) to give a “cis-alpha” isomer. The molecule of complex 5 contains a six-coordinated ruthenium atom chelated by pdto and dpa ligands in the expected distorted octahedral fashion. The 1H and 13C NMR spectral data of the complexes throw light on the nature of metal-ligand bonding and the conformations of the chelate rings, which indicates that the dithioether ligands maintain their tendency to fold themselves even in solution. The bis-mu-chloro dimers 1 and 2 show a spin-allowed but Laporte-forbidden t 2g6 (1A1g) ? t 2g5 eg1 (1T1g, 1T2g) d-d transition. They also display an intense Ru(ii) dpi ? py/bzim (pi*) metal-to-ligand charge transfer (MLCT) transition. The mononuclear complexes 3-8 exhibit dpi ? pi* MLCT transitions in the range 340-450 nm. The binuclear complexes 1 and 2 exhibit a ligand field (3MC) luminescence even at room temperature, whereas the mononuclear complexes 3 and 4 show a ligand based radical anion ( 3MLCT) luminescence. The binuclear complexes 1 and 2 undergo two successive oxidation processes corresponding to successive Ru(ii)/Ru(iii) couples, affording a stable mixed-valence RuIIRuIII state (Kc: 1, 3.97 ¡Á 106; 2, 1.10 ¡Á 106). The mononuclear complexes 3-7 exhibit only one while 8 shows two quasi-reversible metal-based oxidative processes. The coordinated ‘soft’ thioether raises the redox potentials significantly by stabilising the ‘soft’ Ru(ii) oxidation state. One or two ligand-based reduction processes were also observed for the mononuclear complexes. The Royal Society of Chemistry 2006.

A toolbox of building blocks, linkers and crystallisation methods used to generate single-chain magnets

Single-molecule magnets (SMMs) and single-chain magnets (SCMs) are potential candidates for more dense data storage and quantum computing as well as providing interesting systems with which to study the physics behind molecular magnetism. Despite only being discovered in 2001, the field of SCM is experiencing rapid growth and already shows promise with regard to improving on the blocking temperatures (TB) achievable by SMMs. Indeed, to date, the record TB values for SCMs vs SMMs are running neck and neck, at 14K vs 13.9K, respectively. This review details the range of building blocks and linkers that, prior to 1 January 2014, have been used to prepare complexes that were reported to be SCMs. Then, as X-ray structure determinations are of crucial importance, a summary of the crystallisation methods that can be used to assemble the building blocks (usually Ising centres) and linkers into 1D chains, in the form of single crystals, is provided. A table summarising the building blocks/linkers and crystallisation methods, CSD codes, and key magnetic parameters, for the SCMs reported pre-2014, is provided as a useful resource for researchers in this field. The reader is referred to previous excellent reviews for a description of the theory and terms used in the field of SCM: this review instead takes a synthetic chemists perspective, presenting the components and crystallisation methods employed to generate complexes reported to be SCMs, pre-2014.

Synthesis, crystal structure, EPR and electrochemical studies of copper(II) dipicolinate complex with 2,2?-dipyridylamine ligand

The (2,2?-dipyridylamine)(pyridine-2,6-dicarboxylato)copper(II) trihydrate complex was synthesized and characterized by spectroscopic (IR, UV-vis, EPR), X-ray diffraction technique and electrochemical methods. The copper(II) center is surrounded by one bidentate 2,2?-dipyridylamine (dpa) and one tridentate dipicolinate (dpc) ligand, and exhibits a distorted square-pyramidal geometry. The crystal packing involves both hydrogen-bonding and pi-pi interactions. The solvent water molecules link monomers to one another through hydrogen-bonding interactions, forming ladder-type chains in the ab plane. pi-pi interactions also occur between the dpa rings of neighboring molecules and are responsible for interchain packing. Based on EPR and optical absorption studies, spin-Hamiltonian and bonding parameters have been calculated. The g-values, calculated for title complex in polycrystalline state at 298 K and in frozen DMF (110 K), indicate the presence of the unpaired electron in the dx2 – y2 orbital. The evaluated metal-ligand bonding parameters showed strong in-plane sigma- and pi-bonding. The cyclic voltammogram of the title complex investigated in DMF (dimethylformamide) solution exhibits only metal centered electroactivity in the potential range ¡À1.25 V versus Ag/AgCl reference electrode.

Supramolecular assembly of linear trinickel complexes incorporating metalloporphyrins: A novel one-dimensional polymer and oligomer

One-dimensional polymeric or oligomeric chains, in which various linear trinickel complexes linked to the axial sites of metalloporphyrins by the combination of self-assembly and coordination chemistry, have been constructed. A carboxylate group of carboxylpyridine was attached to the end of linear trinickel complexes to produce the linear building blocks, Ni 3(dpa)4X2 [X = 4-PyCOO- (1) or 3-PyCOO- (2)], which was then reacted with metalloporphyrins to form stable polymers or oligomers. The new self-assembled oligomeric chain, [Ni 3(dpa)4(4-PyCOO)2][ZnTPP]2 (3), and two novel self-assembled one-dimensional polymeric chains, {[Ni 3(dpa)4(4-PyCOO)2[MnTPP]}n(ClO 4)n (4), and {[Ni3(dpa)4(3-PyCOO) 2][MnTPP]}n(ClO4)n (5), [dpa – = di(alpha-pyridyl)amido anion; TPP = meso-tetraphenyl- porphyrinato dianion], have been synthesized and their structures were determined by X-ray diffraction. The UV/vis spectra indicate the absence of any noticeable interactions between the linear trinickel units and metalloporphyrins in these chains. The magnetic susceptibility measurements in the solid state show that both polymers 4 and 5 have a very weak ferromagnetic interaction. The Royal Society of Chemistry 2003.

High spin ground state copper(II) and nickel(II) complexes possessing the 3,5-di-tert-butyl-1,2-semiquinonate radical anion

Several high spin ground-state compounds based upon ferromagnetic coupling between a metal ion and the chelating 3,5-di-tert-butyl-1,2-semiquinonate radical anion, [DTBSQ][rad]?, as they possess unpaired electron spins in orthogonal dx2?y2/dz2 and pi? orbitals, are described. [CuII(DPyA)(DTBSQ)](ClO4) (DPyA?=?2,2?-dipyridylamine) was reinvestigated and its singlet excited state is 282?cm?1 [0.035?eV; J/kB?=?406?K (H?=??JSa¡¤Sb)] above the triplet ground state. [CuII(bipy)(DBCat)(MeOH)] (bipy?=?2,2-bipyridine; DBCat?=?3,5-di-tert-butylcatecholate), [CuII(bipy)(DTBSQ)](BF4), [CuII(DPyA)(DTBSQ)-(THF)2](BF4) and [NiII(DPyA)(DTBSQ)(THF)2](BF4) have been structurally characterized and have high spin ground states whose low spin excited states lie 28?cm?1 (0.0034?eV), 382?cm?1 (0.047?eV), 335?cm?1 (0.042?eV), and 108?cm?1 (0.013?eV) higher, respectively. The triplet-singlet separation is 18% greater for [CuII(DPyA)(DTBSQ)(THF)2]+ than [CuII(DPyA)(DTBSQ)]+ and is ascribed to greater orthogonality of the CuII dx2?y2/dz2 and [DTBSQ][rad]? pi? orbitals for octahedral [Cu(DPyA)(DTBSQ)(THF)2]+ with respect to distorted square pyramidal structure of [Cu(DPyA)(DTBSQ)]+. This greater energy of the excited state correlates with the shorter than average M-ODTBSQ distance, i.e. [Cu(bipy)(DTBSQ)]+?>?[CuII(DPyA)(DTBSQ)(THF)2]+?>?[Ni(DPyA)(DTBSQ)(THF)2]+. The order of magnitude lower value for [CuII(bipy)(DBCat)(MeOH)] arises from a weak intradimer S?=?1/2 Cu(II) interaction, not via ferromagnetic coupling between the S?=?1/2 Cu(II) and [DTBSQ][rad]? sites.
