The title copper complex, Cu[CH(3)CO-CH=C(CH(3))N(CH(2)-CH(2))N(CH(3))C=CHCO CH(3)], has been synthesized by the reaction of ligand, 4-[2-(1-methyl-3-oxo-but-1-enylamino)-ethylamino]-pent-3-en-2-one (ONNO) and copper chloride. The structure of the synthesized complex was determined by IR, NMR, mass spectroscopic data and X-ray crystallography. The structure was solved in monoclinic, space group P2(1)/n with a = 10.971 (4), b = 8.988 (3), c = 12.830 (5) , beta = 93.512 (5), V = 1,262.7 (6) (3), Z = 4 and with R (int) = 0.047. The geometry around the copper atom displays a distorted square-planner structure by coordinating with two oxygen atoms from carbonyl moiety and two nitrogen heteroatom from the central moiety of the ligands and thus established two 6-membered rings and one 5-membered ring. The two nitrogen atoms form two anionic-cationic bonds to complete the coordination sphere around the copper metal atom.
