Synthesis and antibacterial evaluation of ligand 3-(2-amino-5-b-benzoyl-phenylimino)-1,3-dihydro-indol-2-one and its complexes with ions of Co(II), Ni(II), Cu(II), and Zn(II).

A new compound 3-(2-amino-5-b-benzoyl-phenylimino)-1,3dihydro-indol-2-one have successfully synthesized from the reaction of isatin with 3,4-diaminobenzophenone. This compound was used as a ligand to the synthesis of novel complexes through its reaction with transition elements salts such as (CoCl2.6H2O, NiCl2.6H2O, CuCl2.2H2O, and ZnCl2). The new complexes had been distinguished using UV-Vis, FTIR, atomic absorption spectroscopy, element analysis, magnetic susceptibility, and conductivity measurements. The physical properties of ligand and the complexes were determined by melting points, and colors. On the other hand, two types of bacteria (E.Coli) and (S. Aureus) used to estimate the biological activities of the ligand and its complexes. [ABSTRACT FROM AUTHOR]
