The obtained azo compound was characterized by micro elemental Analysis, FT-IR, UV-Vis 1H-NMR, and mass spectroscopy. The reaction of this azo ligand with Mn(II), Fe(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Hg(II) chloride salts produced eight heteroleptic complexes. These metal-azo chelate compounds were characterized using flame atomic absorption, elemental Analysis, FT-IR and UV-Vis spectroscopic methods as well as magnetic susceptibility and conductivity measurements. From the obtained data the octahedral structure was suggested for Mn(II), Fe(II), Co(II), Ni(II) and Cu(II) metal ion complexes with general formula [ML2Cl2].H2O and tetrahedral geometry for Zn(II), Cd(II) and Hg(II) metal ion complexes with general formula [MLCl2].H2O
