Polymeric Complex of Mn(II), Co(II), Ni(II), Cu(II) and Zn(II) with Schiff Bases Derived from Hydroquinone bis-(Acetylhydrazide) and Aromatic Aldehydes

Abstract

Complexes of the general formula, M[C₆H₄{OCH₂C(O) NH(N)=CHR}₂ (AcO)₂]_n [where M = Mn(II), Co(II), Ni(II), Cu(II) and Zn(II) and R = -C₆H₄OH, -C₆H₄CH₃ and -C₆H₅] were prepared by the reaction of divalent metal acetates with respective hydroquinone bis-(acetylhydrazide-2-arylaldehyde). These complexes have been characterized on the basis of the elemental analysis, magnetic susceptibility and infrared spectral studies. The magnetic moment data indicate an octahedral geometry for the metal complexes.
