摘要
Three new transition metal complexes have been synthesized with a Schiff base, 3-(2-hydroxy-5-chlorophenylimino)-1,3- diphenylpropen-l-one. In all complexes Schiff base is completely deprotonated and coordinated to metal as tridentate ligand via phenolic and enolic oxygens and imine nitrogen. Thermal decomposition of the complexes has been studied by thermogravimetry. The in vitro antibacterial activity of Schiff bases and their complexes has been evaluated and compared with the standard drugs.
