Synthesis & characterization of transition metals complexes with ferrocenyl schiff bases

Schiff bases and their complexes are versatile compounds synthesized from the condensation of an amino compound with carbonyl compounds and widely used for industrial purposes and also exhibit a broad range of biological activities including antifungal, antibacterial, antimalarial, antiproliferative, anti-inflammatory, antiviral, and antipyretic properties. A few ferrocenyl Schiff bases have been isolated by the condensation of Formyl ferrocene and acetyl ferrocene with 4-methyl ortho-phenylene diamine, orthoamino naphthol and ortho-amino naphthoic acid. Reactions of these ferrocenyl Schiff bases with copper(II) cobalt(II) and nickel(II) salts in varied reaction conditions, Yield new complexes of the type M(L)2 and also some mixed ligand complexes of the type M(L)(X)(NH3) (where HL is mono basic bidentate ferrocenyl Schiff base, M=Ni(II), Cu(II), Co(II) and X=(OH/Cl). Cobalt (III) complexes of the type Co(L)2(OH)(NH3) are also isolated. The compounds have been characterized on the basis of elemental analysis, molar conductance, molecular weights, magnetic susceptibilities and spectroscopic (Electronic and infrared) data.
