The hydrothermal reaction of copper chloride dihydrate and 5,5-dimethyl-imidazolidine-2,4-dione with a mole ratio of 1:1 in acetonitrile resulted in the formation of a new acetate-bridged dinuclear copper complex, C2H6ON2Cu2Cl2(μ-CH3COO)4.Protonated acetamide in enolic form and acetic acid were yielded by the hydrolysis of acetonitrile under hydrothermal condition.The title complex(C12H24Cl2Cu2N2O10) was characterized by X-ray single-crystal diffraction, IR spectrum, elemental and electrochemical analysis.It crystallizes in the monoclinic system, space group P21/c with a = 8.2980(14), b = 14.358(2), c = 12.0010(2) , β = 130.620(3)°, V = 1085.3(2) 3, Dc = 1.696 g/cm3, Mr = 554.31, Z = 2, F(000) = 564 and μ = 2.254 mm-1.The crystal structure consists of a tetraacetate-bridging dinulcear copper complex anion Cu2Cl2(μ-CH3COO)42-, with the chlorine anions in the axial positions, and two protonated acetamide cations C2H6ON+, which were connected through hydrogen bonds to form a three-dimensional infinite network.
