Synthesis, characterization and antimicrobial activity studies of some Schiff base complexes of Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Hg(II) derived from 3-chloro-N'-[(1E,2E)-3-phenylprop- 2-en-1-ylidene]-1-benzothiophene-2-carbohydrazide

Complexes of Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Hg(II) with the Schiff base derived from 3-chlorobenzo(b)thiophene-2-carbohydrazide and cinnamaldehyde has been synthesized and characterized on the basis of elemental analysis, electrical conductance, ESR,XRD, IR, FAB-MASS, TGA, 1HNMR, electronic spectra and magnetic susceptibility measurements. The Schiff base behaves as bidentate ligand coordinating through ON donor site and forms the complexes of the typesML2.(H2O)n.Cl2 (where, L= Schiff base, M=Metal). The complexes are non electrolytes, monomers and octahedral in nature. The ligand and its complexes have been screened for their antimicrobial activity.
