ABSTRACT:
Novel transition metal Cu(II), Ni(II), Co(II) and Zn(II) ions complexes of bidentate Schiff base ligand obtained from 4-Methyl 7-hydroxy 8-formyl coumarin, and Dimethylamino propylene diamine have been prepared and characterized by physical, spectral and analytical data. The synthesized Schiff base act as bidentate ligand for the complexation reaction with Cu(II), Ni(II), Co(II) and Zn(II) ions. The new compounds, possessing the general formula [M(L)2.2H2O] where [M= Cu(II), Ni(II), Co(II) and Zn(II)] show octahedral geometry. In order to evaluate the effect of metal ions upon chelation, the Schiff base and their metal complexes have been screened for antimicrobial activity. The transition metal complexes have shown enhanced antimicrobial activities as compared to Schiff base.
