Abstract
A series of transition elements complexes with [2,6-diacetimino-pheylenediamine –
[2,2,diyl] pyridine] of the general formula [MLCl]Clx, (where M= Cr(III), Pb(II), Zn(II) and
Cd(II), x= 2 for Cr(III)) respectively have been synthesized and fully characterized on the
bases of C.H.N.M, elemental analysis, 13C NMR, UV- Visible and FTIR spectra , in addition
the structure of complexes was characterized by magnetic moments and molar
conductance in DMF solution ,and molar ratio of complexes were also determined. On the
basis ofelectronic spectral studies .All complexes have an octahedral geometry around the
metal center in (1:1) (L:M).
A theoretical treatment of the formation of complexes in the gas phase was studied, this
was done using the HYPERCHEM-6 program for the Molecular mechanics and Semiempirical
calculations. The batch adsorption method has applied on N5 polydentate ligand
to remove the selected toxic metal ions from waste water after immobilization the newly
n5-ligand on silica gel by physic-chemical method.
