Syntheses,characterization,and antimicrobial screening of N-(benzothiazol-2-yl)benzenesulphonamide and its Cu(I),Ni(II),Mn(II),Co(II) and Zn(II) complexes

N-(benzothiazol-2-yl)benzenesulphonamide (bs2abt) was synthesized by the condensation (by refluxing) of 2-aminobenzothiazole and benzenesulphonylchloride in acetone at 140°c. the resulting crude precipitates were recrystallized from dimethylformamide (dmf). five metal complexes of copper(i),nickel(ii),manganese(ii),cobalt(ii) and zinc(ii) of the ligands were synthesized. the compounds were characterized using magnetic susceptibility measurements,uv/vis spectrophotometry,infra red,proton and 13c nmr spectroscopies. the antimicrobial tests of the ligands and its metal complexes were carried out on both multi-resistant bacterial strains isolated under clinical conditions and cultured species using agar-well diffusion method. the multi-resistant bacterial strains used were escherichia coli,proteus species,pseudomonas aeroginosa and staphylococcus aureus which were isolated from dogs. the culture species were pseudomonas aeruginosa (atcc 27853),escherichia coli (atcc 25922) staphyl © 2012 hindawi publishing corporation.
