A series of transition elements complexes with [2, 6-diacetimino-pheylenediamine –[2, 2,diyl] pyridine ]of the general formula [MLCl]Cl, M= Zn(II), Cd(II), Hg(II) and [CrLCl]Cl2, 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 DMSO solution, and molar ratio of metal were also determined. The obtained data of spectra in conjugation with microelemental analyses suggested the octahedral symmetry for all the complexes since the molar ratio(M: L) is 1:1, and the newly ligand behaved as neutral pentadentate through four nitrogen atoms of NH2,C=N and pyridine ring on the basis of infrared spectroscopy and other analysis of molar conductance and magnetic moments for solid complexes. 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 Semi-empirical calculations.
