Synthesis and Investigations of Some New Homobimetallic Complexes Involving Schiff Base Derived From Diketone and Amine

Abstract

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.
