SYNTHESIS, CHARACTERIZATION AND ANTIMICROBIAL STUDY OF Cu(II), Ni(II), Co(II) AND Zn(II) ALDIMINE METAL COMPLEXES

Aldimine ligand 2-Hydroxy-5- bromo-benzylidene-4-hydroxy-aniline (L) and its complexes with Cu (II), Ni (II), Co (II) and Zn (II) were prepared and characterized by analytical, spectroscopic (IR, UV-Vis) techniques, thermal study, electrical conductivity and magnetic measurements. The results indicate that the ligand coordinate through azomithine nitrogen and oxygen of enolic group. The complexes were further screened for antimicrobial activity.
