Abstract
N-Pyridin-2-ylmethyl-benzene-1,2-diamine (L) was prepared from the reaction of ortho
amino phenyl thiol with 2 – amino methyl pyridine in mole ratio (1:1) . It was characterized
by elemental analysis (C.H.N) , FT-IR , Uv – Vis , 1H , 13C-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.
