Abstract

New schiff base bis (salicylidene) tetramethylbenzidine (bstmb) was prepared via the condensation of salicylaldehyde with 3, 3−, 5,5−-tetramethylbenzidine in an ethanol solution. Four complexes were prepared by reaction of schiff base with metal acetat where m(ii),[co, ni, cu, and zn]. The schiff base ligand and their complexes were characterized by using infrared, 1h nmr spectroscopy, uv-visible spectra, solubility, melting point, (c.h.n) analysis, and molar conductance. The potentiometer analysis of the metal complexes revealed 1:1 (schiff base: metal particle) stoichiometry.
