The reactions of transition metal salts with monofunctional bidentate thiosemicarbazone (TSCZH) derived from the condensation of 6-nitro-1H-indole 2-3 dione with thiosemicarbazide have been carried out in 1:2 molar ratio. Derivatives of the type [M(TSCZH)2 .xH2O] Cl (where M=Ti (III), V (III), Mn (III), Co (III), Ru (III), Fe (III) Mo O2(V) and Mo O2(VI) have been obtained. All these complexes are coloured solids and monomeric in nature. Octahedral geometry has been proposed for these complexes based on elemental analyses, molar conductance, magnetic susceptibility and spectral studies. Antimicrobial effects of the ligand and its complexes on different species of pathogenic fungi and bacteria have been recorded.
