چکیده

Synthesis and characterization of Schiff base with solid metal complexes derived from Vanillin and 2-amino-2ethyl-1, 3-propanediol (VAEPD) has been carried out. Structural elucidation of the Schiff base and its metal complexes [Cu(II) and Co(II)] were analyzed on the basis of various spectra like IR, electronic absorption spectra, NMR, ESR, TG-DTA and magnetic moments. From the spectral study, monomeric structures of the complexes showed a six-cordinated metal center moiety with an octahedral geometry. In addition the metal complexes were screened for antibacterial activities and the metal complexes showed moderate activity against the organisms Escherichia coli (E.C), Bacillus subtilis (B.S) and Enterobacter aerogenes.
