Aseries of newcoordination complexes ofCo(II),Ni(II),Cu(II), Zn(II),Cd(II) andHg(II)with the Schiff base 3-chloro-Nï‚¢-[(1E)-(3-methoxyphenyl)methylene]- 1-benzothiophene-2-carbohydrazide have been synthesized and characterized by elemental analysis, electrical conductance, electronic spectra, ESR, XRD, IR, FAB-MASS, TGA, 1HNMR andmagnetic susceptibilitymeasurements. The Schiff base behaves as bidentate ON donor ligand and forms the complexes of the types ML2.(H2O)n (Metal-Ligand ratio) stoichiometry and are non electrolytic in nature. It is found that, Co(II),Ni(II), Cu(II), Zn(II), Cd(II) and Hg(II) complexes exhibit octahedral geometry. The ligand and its complexes have been tested for their antimicrobial activity.
