Abstract: Synthesis of some new oxomolybdenum(V) and dioxomolybdenum(VI) complexes with a Schiff base, 3-methoxysalicylaldehydeisonicotinoylhydrazone derived from 3-methoxysalicylaldehyde and isonicotinoylhydrazide are reported. The complexes have been characterized by elemental analyses, molar conductance, magnetic susceptibility data, IR, UV-vis, EPR, 1H NMR and FAB mass spectral studies. The physico-chemical studies and spectral data indicate that the ligand acts as a monovalent tridentate chelating agent. The FAB mass and X-band EPR spectra indicate that the pentavalent Mo in the complex [MoO(MSINH)Cl2] is monomeric in nature. The X-ray diffraction studies of [MoO(MSINH)Cl2] correspond to orthorhombic crystal lattice with unit cell dimensions: a = 8.043Ả, b = 12.49Ả and c = 14.936Ả. All the complexes are found to be neutral with distorted octahedral geometry. The thermal properties of the complex [MoO(MSINH)Cl2] have been investigated by thermogravimetric techniques. The ligand, [MoO(MSINH)Cl2] and [MoO2(MSINH)Cl] have been screened for their in vitro anticancer and antibacterial activity. The complex, [MoO(MSINH)Cl2], exhibits much higher activity than the ligand (MSINH) and its dioxocomplex, [MoO2(MSINH)Cl].
