Synthesis and structural characterization of the dinuclear bis(glutarato)bis(urea)copper(II)complex, dihydrate

摘要

The complex [Cu(OOC-(CH2)3-COO)(O=C(NH2)2]2·2H2O has been synthesized and characterized by X-ray crystallography. It crystallizes in the triclinic system P-1 with a = 8.003(2) Å, b = 8.611(2) Å, c = 8.620(2) Å, α = 96.14(3)°, β = 116.66(2)°, γ = 105.66(4)° and V = 492.9(3) Å3. 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 $cdots $ Cu: 2.6266(15) Å).
