Synthesis, spectroscopic and biological studies of a new some complexes with n-pyridin-2-ylmethyl-benzene-1,2-diamine

Abstract EN

N-Pyridin-2-ylmethyl-benzene-1, 2- diamine (L) was prepared from the reaction of ortho amino phenyl Thiel with 2– amino methyl pyridine in mole ratio (1 : 1).

It was characterized by elemental analysis (C.H.N), FT-IR, Uv-Vis, 1H, 13 C-N.M.R.

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

The structural was established by elemental analysis (C.H.N), FT-IR, Uv-Vis spectra, conductivity measurements, atomic absorption and magnetic susceptibility.

The complexes showed characteristic behavior of octahedral geometry around the metal ions and the (N, N, N) ligand coordinated in tridentat mode except with Pd complexes showed sequare planer.

α, Kf, εmax for the complexes were estimated too.

β for Co-complex was calculated.

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