Abstract
The complexes of Cr(III), Mn(II), Co(II), Ni(II), Cu(II), Zn(II) and Cd(II) with Schiff base ligand, namely 1-phenyl-1-hydrazonyl 2-oximino 1,2-ethanedione (HPHOED) have been synthesized in situ by the reaction of isonitrosoacetophenone (phenyl glyoxaldoxime i.e., Hpgaldox) with hydrazine sulphate and metal chloride. The complexes have been characterized by various physico-chemical methods. The analytical data corresponds to the general formula ML2·xH2O where L is deprotonated ligand HPHOED, M is a divalent metal ion and x = nil or 2 while the Cr(III) complex of the Schiff base ligand can be formulated as CrL2Cl·H2O. The analytical and infrared spectral data also indicates that the ligand HPHOED act as monobasic bidentate ligand. The electrical conductance in nitrobenzene solution indicates their non-electrolytic nature. The room temperature magnetic susceptibility measurements suggest an octahedral geometry for the complexes, which is further supported by their diffuse reflectance spectra. The infrared spectra of the complexes of Cr(III), Cu(II), Zn(II) and Cd(II) with HPHOED indicate bonding through imino nitrogen and oximino oxygen in case of symmetrical structure involving six membered chelate rings while the infrared spectra of the Mn(II), Co(II), Ni(II) complexes of HPHOED indicate bonding through imino and oximino nitrogen in case of an asymmetrical structure involving five and six membered chelate rings.
