| Abstract: | Two binary
copper(II) and nickel(II) complexes viz., [Cu(L)(HL)]NO3.H2O
(1) and [Ni(L)(HL)]NO3.H2O (2) of hydrazone Schiff base
ligand (where L/HL = N'-[phenyl(pyridin-2-yl)methylidene]benzohydrazone)
have been synthesized and characterized. Both the complexes (1) and (2) and ligand (HL) are structurally characterized using single
crystal X-ray diffraction technique. They crystallize in monoclinic crystal
system in the space group P21/n.
The observed trends in spin-Hamiltonian parameters g║>g┴>2.03
indicates a dx2-y2 ground state in complex (1). In the absorption
spectra in 100% DMSO, complex (2) exhibits a d-d transition at ~900
nm, which is assigned to ν1 band (3A2g→3T2g
in octahedral parentage). Superoxide dismutase activities of both complexes
reveal the dismutation of superoxide (O2-). |
