Metal complexes with mono- and bis{[bis(2-pyridyl)amino]carbonyl}ferrocene ligands

The ligands {[bis(2-pyridyl)amino]carbonyl}ferrocene (L1) and 1,1?-bis{[bis(2-pyridyl)amino]carbonyl}ferrocene (L2) have been prepared by treatment of the mono- or 1,1?-bis(chlorocarbonyl)ferrocene derivatives with dipyridylamine in a 1:1 or 1:2 ratio, respectively. The ligand properties of these compounds towards group 11 and palladium complexes have been studied. Ligand L1 coordinates to these compounds to give four-coordinate [Cu(L1) 2]+, [PdCl2(L1)] and [Ag(OTf)(L1)(PR 3)] or three-coordinate [Ag(OTf)(L1)] and [Au(C6F 5)(L1)] compounds. The ligand coordinates in a chelate fashion in all cases. The reactivity of L2 is somewhat different because coordination to copper or silver atoms can take place through several pyridine units either from different cyclopentadienido rings, as in [Cu(L2)]+, [Ag 2(OTf)2-(L2)] and [Ag(OTf)(L2)(PPh3)], or from the same cyclopentadienido ring, as in [Ag2(OTf)2(L2) (PPh3)2]. Coordination as a bridging ligand for four gold atoms has also been achieved in [Au4(C6F5) 4(L2)] and [Au4(L2)(PPh3)4](OTf) 4. The ligands and some complexes have been characterized by X-ray diffraction studies and show the presence of several hydrogen bonds that lead to supramolecular structures. Wiley-VCH Verlag GmbH & Co.

(Azido-kN)bis-(di-2-pyridylamine)-copper(II) hexa-fluoro-phosphate and (azido-kN)bis-(di-2-pyridylamine)-copper(II) chloride tetra-hydrate

Both complexes display a distorted square-pyramidal geometry. Each Cu atom is coordinated in the basal plane by three dpyam N atoms and one azide N atom in equatorial positions, and by another N atom from the dpyam group in the apical position. In complex (I), the one-dimensional supra-molecular architecture is assembled via hydrogen-bonding inter-actions between the amine N atom and terminal azide N atoms and the F atoms of the PF6 – anion. For complex (II), hydrogen-bonding inter-actions between the amine N atom, the Cl- anion and water O atoms result in a two-dimensional lattice.

Synthesis and structural characterization of a linkage isomer to a mononuclear Nickel(II) complex: Experimental and computational depiction of phosphoesterase efficiency

Synthesis and structural characterization of a linkage isomer, bis(2,2?-dipyridylamine)dithiocyanato(k-S)nickel(II), [Ni(dpa)2(k-SCN)2] (1) of a previously reported Ni(II) complex, [Ni(dpa)2(k-NCS)2] (dpa = 2,2?-dipyridylamine; SCN = thiocyanate) has been reported herein. X-ray structural analysis of 1 reveals that Ni(II) complex crystallizes in monoclinic system with P21/c space group and exists in trans configuration. The coordination geometry for 1 adopts a tetragonal structure. Supramolecular aspects of the Ni(II) complex indicate that N atom of SCN behaves as a donor and H atom of dpa ligand acts as a receptor in growing 1D crystalline structure along b axis in solid state. The aromatic rings in 1 prefer to exist in face-centred stacking with interplanar distance of 3.426 A and supports strongly to form self-assembled 3D crystalline architecture. Hirshfeld surface analysis further recommends this crystalline assembly in solid state. 1 exhibits promising phosphatase activity towards disodium(4-nitrophenyl)phosphate (PNPP) in aqueous-methanolic medium. The hydrolytic phosphatase efficiency for 1 is determined in terms of turnover number (kcat) as 3.38 ¡Á 104 h?1. Moreover, density functional theoretical computations closely replicate the structural parameters and spectroscopic behaviour of 1.

Synthesis of mixed-ligand complexes of copper(II) with lactate and 2,2-dipyridylamine: Study of the effect of weak interactions on their crystal packing

The supramolecular association in these complexes have also been analyzed. In both cases the copper(II) ion is in a slightly distorted square-pyramidal environment. The twocomplexes are extended into 3D networks, through hydrogen bonding alone in 1 and through both hydrogen bonding and pi-pi interactions in 2.

Oxidation chemistry of axially protected Mo2 and W2 quadruply bonded compounds

Reported is a facile, high-yielding one-pot synthesis of the quadruply bonded ditungsten (II,II) compound W2(dpa)4 (1) (dpa=2,2?-dipyridylamide), which was obtained from W(CO)6 at high temperature in naphthalene. A similar reaction in 1,2-dichlorobenzene furnished a ditungsten (III, III) species as the major product that was crystallized as [W2(dpa)3Cl2][BPh4] (3). The [W2(dpa)3Cl2]+ cation is better prepared by oxidation of 1 with SO2Cl2. Compound 1 was characterized by X-ray crystallography and cyclic-voltammetry, and is compared with its earlier reported molybdenum analogue, Mo2(dpa) 4 (2). One-electron oxidation products of 1 and 2, [W 2(dpa)4][BPh4] (1BPh4) and [Mo 2(dpa)4][BPh4] (2BPh4), respectively, have also been synthesized. The crystallographically determined metal-metal distances of 2.23 A and 2.14 A in 1BPh4 and 2BPh4, respectively, are in agreement with metal-metal bond orders of 3.5. Unlike most previously reported Mo25+ and W 25+ compounds, the primary coordination spheres around the M2-units in 1/1BPh4 and 2/2BPh4 remain unchanged upon one-electron oxidation, because the tridentate dpa ligand hinders axial coordination of exogenous ligands.

Synthesis and photoluminescence properties of four rhenium(I) complexes based on diimine ligands with oxadiazole/carbazole moiety

By introducing two carrier-transporting moieties (oxadiazole and carbazole) into two diimine ligands (2-(2-pyridine)-benzimidazole and 2,2′-dipyridylamine), respectively, four novel ligands (L1-L4) and their corresponding rhenium(I) complexes (1-4) have been synthesized and characterized by elemental analysis, 1H NMR and IR spectra. Their photophysical properties, thermal analysis, along with the X-ray crystal structure analysis of L4 and corresponding complex 4 are also described. In absorption spectra, the 2-(2-pyridine)-benzimidazole containing complexes 1, 2 show the intraligand charge-transfer (pi?pi*(L)) bands and metal-to-ligand charge-transfer dpi(Re)?pi*MLCT bands, while the 2,2′-dipyridylamine containing complexes 3, 4 only show the pi?pi*bands. In the excitation spectra, all the complexes show strong MLCT bands. After excitation of pi?pi*or MLCT bands, all the four Re(I) complexes exhibit broad bands around 550-560nm due to the Re(I)-based 3MLCT emission. The two complexes 1 (with oxadiazole moiety) and 2 (with carbazole moiety) show the photoluminescence quantum efficiency of 2.0% and 7.5% in solid state, respectively, indicating that the carbazole unit is the better chromophore to enhance the luminescence efficiency of diimine Re(I) complexes than the oxadiazole moiety.

Zinc complexes of salicylaldehydes: Synthesis, characterization and DNA-binding properties

The neutral mononuclear zinc complexes with substituted salicylaldehydes, in the absence or presence of a nitrogen donor heterocyclic ligand 2,2?-bipyridine or 1,10-phenanthroline or 2,2?-dipyridylamine, have been synthesized and characterized by IR, UV and NMR spectroscopies. The experimental data suggest that salicylaldehyde is on deprotonated mode acting as a bidentate ligand coordinated to the metal ion through the phenolato and one aldehydo oxygen atoms. The crystal structures of bis(5-nitro-salicyladehydato) (2,2?-dipyridylamine)zinc(II), bis(5-chloro-salicylaldehydato)(2,2?- bipyridine)zinc(II) monohydrate and bis(5-bromo-salicyladehydato)bis(methanol) zinc(II) have been determined with X-ray crystallography. The ability of the complexes to bind to calf-thymus DNA (CT DNA) has been studied by UV and fluorescence spectroscopy and viscosity measurements. UV studies of the interaction of the complexes with DNA have shown that they can bind to CT DNA. The calculated binding constants of the complexes to DNA reveal tight binding to DNA. The complexes can probably bind to CT DNA via intercalation as concluded by studying the viscosity of a DNA solution in the presence of the complexes. Competitive studies with ethidium bromide (EB) have shown that the complexes can displace the DNA-bound EB suggesting strong competition with EB for the intercalation site of DNA.
