Synthesis and Characterization of CoII, NiII, CuII and ZnII. Schiff Base Complexes and Their Microbial Activities
BN Muthal, BN Raut
Abstract: A newly synthesized Schiff bases N-bis-(salicylidene)-2-4-diamino-5-chlorothiazole and N-bis-(5-methylsalicylidene)-2-4 diamino-5-chloro-thiazole and metal ion CoII, NiII, CuII and ZnII, their metal complexes have been reported. The complexes are characterized by elemental analysis, UV-visible and infrared spectra, magnetic susceptibility and conductivity measurement. The Schiff base act as monomeric as well as dimeric to CoII, CuII and NiII, ZnII respectively. The ligand coordinate though oxygen atom of phenolic OH group and the nitrogen atom of azomethine group. The complexes are non-electrolytic in nature. The Schiff bases and their metal complexes were screened for antibacterial fungicidal and pesticidal activity.
