The syntheses and characterization of a series of dinuclear mu-oxalato copper(II) complexes of the general type [(NN)1 or 2Cu(C2O4)Cu(NN)1 or 2]2+, where NN=didentate dpyam (di-2-pyridylamine) ligand, are described. The crystal structures of three representative complexes have been determined. The dinuclear-oxalate bridged compounds [Cu(dpyam) 4(C2O4)](ClO4)2(H 2O)3 (1) and [Cu2(dpyam)4(C 2O4)](BF4)2(H2O) 3 (2) crystallize in the non-centrosymmetric triclinic space group P1 which are isomorphous and isostructural. The compound [Cu 2(dpyam)2(C2O4)(NO3) 2((CH3)2SO)2] (3) crystallizes in the centrosymmetric monoclinic space group P1 with all Cu-oxalate contacts in the equatorial plane. All three complexes contain six-coordinate copper centres bridged by planar bis-didentate oxalate groups from the equatorial position of one chromophore to the equatorial position of the other one. Both chromophores in 1 and 2 exhibit the compressed octahedral Cu(II) geometry, while 3 displays an elongated octahedral Cu(II) environment. The IR, ligand field and EPR measurements are in agreement with the structures found. The magnetic susceptibility measurements, measured from 5 to 280 K, revealed a very weak ferromagnetic interaction between the Cu(II) atoms for compound 1 and 2, with a singlet-triplet energy gap (J) of 2.42 and 3.38 cm-1, for compounds 1 and 2, respectively. Compound 3 has a strong antiferromagnetic interaction with a J of -305.1 cm-1, in agreement with coplanarity of the magnetic orbitals.

Access to well-defined heterogeneous catalytic systems via ring-opening metathesis polymerization (ROMP): Applications in palladium(II)-mediated coupling reactions

The preparation of a new heterogeneous palladium(II)-based catalyst and its homogeneous analogue and their use for Heck-type, alkyne and amine couplings are described. The heterogeneous catalytic system is based on a polymer-bound dichloropalladium di(pyrid-2-yl)amide and was prepared via ring-opening metathesis copolymerization of norborn-2-ene-5-(N,N-di(pyrid-2-yl))carbamide with 1,4,4a,5,8,8a-hexahydro-1,4,5,8-exoendo-dimethanonaphthalene and subsequent loading of the resulting resin with palladium(II) chloride. The heterogeneous catalyst is air, moisture, and temperature stable up to 150 C and highly active (94-99% yields) in the vinylation of aryl iodides and aryl bromides (Heck-type couplings) with turn-over numbers (TONs) of up to 210000. Even higher TON’s (up to 350000) may be achieved in the arylation of alkynes. High yields (?95%) and TONs (?24000) may additionally be achieved in the tetrabutylammonium bromide (TBAB) assisted vinylation of aryl chlorides. Moderate yields (<65%) and TONs (<4000) are observed in the amination of aryl bromides. A soluble analogue of the heterogeneous system, N,N-di(pyrid-2-yl)acetamide palladium dichloride (2), was prepared from palladium(II) chloride and N,N-di(pyrid-2-yl)acetamide (1) and characterized by X-ray analysis. 2 crystallizes in the monoclinic space group P21/n, a = 835.0(1) pm, b = 1494.3(4) pm, c = 1199.3(2) pm, alpha = 90, beta = 109.05(2), gamma = 90, Z = 4. It served as a model compound for the elucidation of the actual geometry of the catalytic species. The unstrained geometry of 2 with almost ideal angles and bond lengths explaines the high stability of the catalytic center. The significantly higher catalytic activity of the heterogeneous system compared to the homogeneous one suggests well-defined ligand-bound catalytic sites rather than polymer-supported palladium colloids.

Influence of Ancillary Ligands in Dye-Sensitized Solar Cells

Dye-sensitized solar cells (DSSCs) have motivated many researchers to develop various sensitizers with tailored properties involving anchoring and ancillary ligands. Ancillary ligands carry favorable light-harvesting abilities and are therefore crucial in determining the overall power conversion efficiencies. The use of ancillary ligands having aliphatic chains and/or phi-extended aromatic units decreases charge recombination and permits the collection of a large fraction of sunlight. This review aims to provide insight into the relationship between ancillary ligand structure and DSSC properties, which can further guide the function-oriented design and synthesis of different sensitizers for DSSCs. This review outlines how the new and rapidly expanding class of chelating ancillary ligands bearing 2,2?-bipyridyl, 1,10-phenanthroline, carbene, dipyridylamine, pyridyl-benzimidazole, pyridyl-azolate, and other aromatic ligands provides a conduit for potentially enhancing the performance and stability of DSSCs. Finally, these classes of Ru polypyridyl complexes have gained increasing interest for feasible large-scale commercialization of DSSCs due to their more favorable light-harvesting abilities and long-term thermal and chemical stabilities compared with other conventional sensitizers. Therefore, the main idea is to inspire readers to explore new avenues in the design of new sensitizers for DSSCs based on different ancillary ligands.

Mixed ligand binuclear alkoxo-bridged copper(II) complexes derived from aminoalcohols and nitrogen ligands

Six binuclear alkoxo-bridged complexes have been obtained and cystallographically characterized. The binuclear species are spontaneously assembled by reacting copper perchlorate with an aminoalcohol (monoethanolamine, Hmea, or propanolamine, Hpa) in the presence of various co-ligands: 4-phenyl-pyridine (4-phpy) 4-amino-pyridine (4-apy) dipyridylamine (dpyam), 2,3-bis(2-pyridyl)pyrazine (dpp). The six new compounds have the following formulas: [Cu(mea)(4-phpy)(ClO4)]2 1, [Cu(pa)(4-phpy) 2]2(ClO4)2 2, [Cu(pa)(4-apy) (ClO4)]2 3, [Cu(mea)(dpyam)]2(ClO 4)2 4, [Cu(pa)(dpyam)]2(ClO4) 2 5, and [Cu(mea)(dpp)]2(ClO4) 2¡¤CH3OH 6. Except compound 1, the binuclear entities in crystals 2 – 6 are centrosymmetric, with pentacoordinated copper ions. In compound 1, one copper is pentacoordinated, while the other one is hexacoordinated. The perchlorate ions play different functions (monodentate and bridging in 1, monodentate in 3, uncoordinated in 2, 4, 5 and 6. The magnetic properties of compound 1 have been investigated and reveal a quite strong ferromagnetic coupling between the copper ions (J = + 81.9 cm-1, H = -JS1S2).

New copper(I) halide complexes with 2,2′-dipyridylamine and products oftheir autoxidation. X-ray diffraction structure of a triply-bridged mu-Cl-mu-(OMe)2-dicopper(II) complex

Some new complexes of Cu(I)X (X = Cl, Br, I) with 2,2′- dipyridylamine (dipyam) have been prepared and their autoxidation in methanol has been investigated. The products were characterized by elemental analysis and IR spectroscopy. The X-ray diffraction structure of the [Cu2(mu-OMe)2(mu-Cl)dipyam2]Cl*MeOH (10) complex is reported. Crystals of 10 are orthorhombic, space group Cmc21, with a=14.993(5), b=8.191(4), c=21.237(6)A, Z=4, and R=0.052 for 1482 observed independent reflections. In thedinuclear monocations the triply-bridged Cu(II) ions show a distorted square-pyramidal coordination with four short in-plane bonds involving two N atoms from a terminal dipyam ligand and two O atoms from two bridging methoxy groups. The fifth apical ligand is a longer bonded bridging chloride ion, which joins the basal CuN2O2 planes in a roof-top configuration.

Square planar gold(iii) complexes that contain functionalised bipyridine ligands of general formula [Au(NN)Cl2][PF6] [where NN = 2,2?-bipyridine, 4,4?-dimethyl-2,2?-bipyridine, 4,4?-dimethoxy-2,2?-bipyridine and 4,4?-diamino-2,2?- bipyridine] have been prepared and characterised by NMR spectroscopy and mass spectrometry. Two of the complexes have also been characterised in the solid state by X-ray crystallography. In addition, a gold(iii) compound bearing a dipyridin-2-ylamine ligand was also prepared and characterised. The complexes were found to undergo hydrolysis under pseudo-physiological conditions. Moreover, the complexes showed moderate to good cytotoxicity in vitro towards the A2780 human ovarian carcinoma cell line and the cisplatin resistant variant A2780cisR. Reactivity studies with biomolecules, such as reducing agents, plasmid DNA and a model protein (ubiquitin) were also performed to provide tentative insights into the mode of action of the complexes.
