    In this study the synthesis and characterization of two metal complexes of Ni(ΙΙ) and Cu(ΙΙ) are presented. New Hetrocyclic aromatic complexes of the type [ML2], where M is Ni(ΙΙ) or Cu(ΙΙ) and L is C8H6O2N2 were synthesis by the template method from quinoxaline-2,3-dione, hydroquinone with the corresponding hydrated metal salt of Ni(NO3)2.6H2O and CuCl2.2H2O. The complexes were distinctly colored and stable to atmospheric conditions. The synthesized complexes were characterized by UV, IR, 1HMR, AAS spectroscopic methods as well as by measurements of their respective molar conductance.The analysis result showed the formation of a square planar complexes of both metals with quinoxaline-2,3-dione.
