| Abstract: | A new acetate radical bridged dinuclear copper(Ⅱ ) complex (C8H9NO2)2-Cu2(CH3COO)4] has been synthesized by the reaction of Cu(OAc)2 with pyridine-3-ethyl formate and further characterized by X-ray single-crystal diffraction. Crystal data for the title compound:triclinic system, space group P-1, with a = 8.1654(14), b = 9.7010(16), c = 9.9005(17) (A), α =83.266(2),β = 78.887(2), γ = 72.881(2)°, V = 733.9(2) (A)3, Mr = 665.58, Z = 1, Dc = 1.506 g/cm3,F(000) = 342, μ = 1.510 mm-1, the final R = 0.0392 and wR = 0.1005. According to the structural determination, each unit of the title compound is composed of two Cu( Ⅱ ) atoms, two pyridine-3-ethyl formate molecules and four acetate ions. Each Cu(Ⅱ) coordinates to oxygen atoms of acetate and nitrogen atoms of pyridine- 3-ethyl formate ligand to give a six-coordinate distorted octahedral geometry. It is worth mentioning that strong Cu-Cu bond can be observed in the title compound. |
