摘要：

The complex [Cu(OOC-(CH2)(3)-COO)(O=C(NH2)(2)](2)center dot 2H(2)O has been synthesized and characterized by X-ray crystallography. It crystallizes in the triclinic system P-1 with a = 8.003(2) angstrom, b = 8.611(2) angstrom, c = 8.620(2) angstrom, alpha = 96.14(3)degrees, beta = 116.66(2)degrees, gamma = 105.66(4)degrees and V = 492.9(3) angstrom(3). The structure consists of discrete centrosymmetric binuclear units and water molecules. The Cu(II) ions adopt a square-pyramidal coordination with four oxygen atoms of four bridging carboxylate and one carbonyl oxygen of the monodentate urea ligand. There is a very strong interaction between the two copper centers in binuclear entities (Cu...Cu: 2.6266(15) angstrom).
