A new set of penta-coordinated copper(II) hydrazone complexes containing solvated methanol were synthesized by reacting the ligands, 2-acetylpyridine benzoyl (HL1) and thiophene-2-carboxylic acid (HL2), with [CuCl2(DMSO)2] characterized different spectral methods. Single crystal X-ray diffraction studies revealed that both them, [CuCl(L1)(MeOH)] (1) [CuCl(L2)(MeOH)] (2), have square pyramidal geometry around cupric ion, in which is coordinated through NNO atoms along a molecule apical...
Four new bivalent nickel hydrazone complexes have been synthesised from the reactions of [NiCl2(PPh3)2] with H2L {L = dianion hydrazones derived condensation salicylaldehyde or o-hydroxy acetophenone p-toluic acid hydrazide (H2L1) (1), (H2L2) (2) and naphthaldehyde benzhydrazide (H2L3) (3) (H2L4) (4)} formulated as [Ni(L1)(PPh3)] (5), [Ni(L2)(PPh3)] (6), [Ni(L3)(PPh3)] (7) [Ni(L4)(PPh3)] (8). Structural characterization 5–8 were accomplished by using various physico-chemical techniques. In...
A new series of geometrically different complexes containing ferrocenyl hydrazone ligands were synthesised by reacting suitable precursor complex [MCl2(PPh3)2] with the HL1 or HL2 (where M = Cu(II) Ni(II); [Cp2Fe(CHN–NH –CO– C6H5)] (1) and [Cp2Fe(CHN–NH–CO–C5H4N)]) (2). The composition [Cu(L1)(PPh3)2], (3) [Cu(L2)(PPh3)2] (4), [Ni(L1)2] (5) [Ni(L2)2] (6) characterised various spectral studies. Among them, 3 5 single crystal X-ray diffraction showed a distorted tetrahedral structure for...
Synthesis, spectral, electrochemical and single crystal X-ray diffraction data of a new series DMSO containing bivalent ruthenium hydrazone complexes are presented. XRD two the revealed an octahedral coordination around ion satisfied by NOS2Cl2 atoms. Electrochemical studies showed metal centred, quasi-reversible, one-electron redox behaviour complexes. The binding these with biomolecules such as calf thymus DNA (CT-DNA) bovine serum albumin (BSA) protein investigated different...
