Abstract: Copper (II) complex of N, N-Bis (salicylidene)-2, 4-dihydroxy-5- acetylacetophenone dihydrazone (BSDAAD) was synthesized and characterized by conductivity and magnetic susceptibility measurements, analytical data, IR, UV-Vis and AAS spectroscopic techniques. The Schiff base BSDAAD, was synthesized by the condensation of 2, 4-dihydroxy-5- acetylacetophenone dihydrazone (DAAD) and salicylaldehyde, and characterized by MS, IR, and UV-Vis spectroscopic techniques. The ligand behaves as symmetric, tetrabasic bis-tetradentate system through ONNO donor sequence. The coordination results in a distorted (elongation) octahedral geometry. Subnormal magnetic moment of the dinuclear complex suggests antferromagnetic interaction between the metal ion centers through a possible super exchange mechanism.
