The complexes of the type MLXn where M=Co(III),Fe(III), Mn(III), Ti(III),V(III), Ru(III),Ru(II) MoO(V),MoO2(VI) and UO₂(VI),X=Cl/NO₃, n=2/4, and L is the thiosemicarbazide ligand derived from reaction between benzofuran-2-carboxy hydrazide and phenylisothiocyanate(BCPT)were prepared. All the complexes isolated in solid state, are stable in air and characterized by the elemental analyses, IR, electronic spectral data, magnetic moment and conductance measurement studies. Thiosemicarbazide ligand behaves as bidentate by co-ordinating through oxygen of carbonyl group and nitrogen of hydrazine residue. The probable structure for all the metal complexes are also proposed here. The thiosemicarbazide ligand and its metal complexes have been screened for their antimicrobial activity.
