Schiff Bases and there complexes, syntheses Characterization, and there applications

Abstract

Some Schiff bases were synthesized by condensation of two aldehydes(vanillin ,para-di methyl amino benzaldehyde ) with two amines (Urea, Thiourea),and their complexes with two transition metals (Cu,Co) were also prepared. These compounds were characterized by using IR spectrum,atomic absorption,UV/visible and their melting pointswere also determined . The biological activity of these compounds were tested for bacteria(Ps.aeruyinosa,E.coli, S.aureus,E.faecalis).
