Structural Studies on Metal Complexes of Benzthienoin Oxime

Abstract

Mn(II), Pe(II), Co(II), Ni(II), Cu(II), Zn(II), Pd(II) and Mo(VI) complexes
have been prepared by reacting metal salts with the ligand
benzthienoin oxime in alcoholic medium. All the complexes are coloured
crystalline solids and are non-electrolytes in nitrobenzene. Elemental
analysis confirm the 1 : 1 stoichiometry for Mn(II), Cu(II) and Zn(II)
complexes whiles other metals form 1 : 2 complexes. Magnetic, electronic
and IR spectral information suggest that Mn(II), Cu(II), Pd(II), Ni(II) and
Co(II) exhibit planar geometry while Fe(II) and Mo(VI) crystallise with
octahedral geometry. The tetrahedral environment is suggested for the
Zn(ll) complex.
