Abstract -A Schiff base has been prepared bycondensation of acetylacetone and 2-aminopyridine. Metal complex of the Schiff base was prepared by the reaction of the Schiff base and cobalt(II) chloride in methanol. The complex was isolated, washed and dried. The Schiff base and the complex were yellow and purple colors respectively. They were characterized by solubility test, melting point and decomposition temperature, FT-IR., and molar conductivity analysis. Solubility test on the Schiff base and complex showed that they all soluble in DMF and DMSObut insoluble in CCl4and ether. Also FT-IR. analysis showed a band at 1674cm-1assigned to azomethine of the Schiff base which shifted to 1644cm-1in the complex. The complex is high spin complex and electrolytic in nature.
Keywords: 2-Aminopyridine, Acetylacetone, Cobalt (II) Chloride, Ligand, and Physicochemical Properties.
