Synthesis and Characterization of Schiff Bases Complexes of Divalent Metals

Abstract

This paper reports the synthesis of Mn(II), Fe(II) and cochelates derived from 2,6-diacetyl pyridine dihydrazide and diacetyl with the general composition [M(C₁₃H₁₅N₅)X₂] where, M = Mn²⁺, Fe²⁺, Co²⁺ and X = Cl, Br, NO₃ or NCS. All the chelates were characterized by elemental analysis, molar conductance, magnetic susceptibility measurements, electronic and IR spectral studies. On the basis of these studies, the divalent metal complexes have been assigned trigonal bipyramidal geometry with high spin.
