| 摘 要： | 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 P1,with a=8.1654(14),b=9.7010(16),c=9.9005(17) ,α= 83.266(2),β=78.887(2),γ=72.881(2)o,V=733.9(2) 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.
