Synthesis, Spectral Characterization and 3D Molecular Modeling of Some Novel Nickel(II) Complexes Derived from 4-Aminoantipyrine

Some novel Ni(II) complexes with the ligand (z)-4-((2-hydroxy-4-methoxyphenyl) diazenyl)-1,5-dimethyl-2-phenyl-1H-pyrazole-3(2H)-one, 3-methoxy phenol azoantipyrine, L having the formulae [Ni(L)(2)X-2] and [Ni(L)(2)(Y)Cl] where X = Cl- / NO3; Y = NCS- were synthesized and characterized by elemental analysis, molar conductance measurements, magnetic susceptibility measurements, spectral (IR, UV-Visible, EPR, FAB-mass) studies, thermo gravimetric analysis and by TEM image. Energy minimized configuration of the complex [Ni(L)(2)Cl-2] was made with CHEM Bio 3D Ultra 11.0 and the respective parameters were computed. The ligand and the complex [Ni(L)(2)(Y)Cl] were screened for their antibacterial activities. An octahedral structure is tentatively proposed for the complexes.
