Synthesis and investigations of some new homobimetallic complexes involving Schiff base derived from diketone and amine

Abstract EN

A bidentate Schiff base ligand ; 2, 3-Bis[N-(2, 4 dinitrophenylhydrazineimino) butane (L), and its new homobimetallic complexes have been synthesized and characterized on the basis of analytical, spectral, magnetic and conductance measurements.

The compositions of these complexes are found to be [(M)2L(μ-CH3COO)2(η-CH3COO)2].

XH2O (where M = Co (II) or Cu (II), [(Zn)2L(μ-CH3COO)2(η-CH3COO)2] ; and [(Ni)2L (μ-CH3COO)2(η-CH3COO)2(H2O)4] XH2O.

The overall IR data suggest the bidentate (NN) nature of the ligand and the metal centres are bridged by bidentate CH3COO groups.

The Co (II), Cu (II) and Zn (II) complexes are proposed to be square planar, while the Ni (II) complex is proposed to be octahedral.
