Synthesis, spectroscopic and antibacterial activity study of n-[2 (2-phenyl hydrazinyl)‎ phenyl] benzothiazol-2-amine complexes

الملخص EN

s prepared from the reaction of orthoaminohydrazo benzene with 2-mercaptobenzothiazole in mole ratio (1:1).

It was characterized by elemental analysis (CHN), 1H, 13C-NMR, IR and UV-Vis.

The complexes of the bivalent ions Co(II), Ni(II), Cu(II), Cd(II), Hg(II) and Pb(II) have been prepared and characterized.

The structural feature were established by elemental analysis (CHN), IR, UV-Vis spectra, conductivity measurements, atomic absorption and magnetic susceptibility.

All complexes have been showed octahedral geometry except Cu(II) complex showed square planer.

Dissociation degree, stability constant and molar absorptivity (l.

mol-1.

cm-1) were calculated for all complexes.

The study of biological activity for the ligand (L) and its metal complexes which was showed various activity toward staphylococcus aureus and E.

Coli.
