Synthesis, characterization, and biological activity assessment of new metal complexes of Schiff bases produced from benzoin

By the reaction of Benzoin with melamine and 5-aminosalysilc acid a new Schiff base is obtained legends Mn++, Zn++, Ag + salts leads to complexes [M (L)2 ] X at PH=7-6, PH=9-10, L= BMA, BMS M= Mn++ Zn++ +, Several chemical physical measurements, such as melting point, molar conductivity, magnetic properties, well FT-IR spectroscopy, UV-VIS spectroscopy element analysis (C.H.N.), (1 H-NMR)spectroscopy, GC-MASS. was used identify produced ligands complex structures, Znand ++ give hexacoordinated having shape octane al but Ag+ gives tetracoordinate complexes. tetrahedral. then they were screened for biological activity using agar plate diffusion technique against Gram(+) (Staphylococcus aureus bacteria, pseudomonas aeruginosa bacteria) Gram(−) (Escherichia coli Klebsiella pneumonia When compared streptomycin trimethoprim drug, all these their show good antimicrobial effectualness.
