摘　　要：用溶液法合成了一维配合物[Cu(NPG)2(H2O)2].CH3CH2OH(HNPG=邻苯二甲酰甘氨酸),并对其进行了元素分析,红外光谱,热重分析,磁性和X射线单晶衍射实验。单晶结构分析表明该晶体属于三斜晶系,P-1空间群,晶胞系数a=0.47674(12)nm,b=0.11319(3)nm,c=0.11614(3)nm,α=106.468(4)°,β=100.114(5)°,γ=94.358(5)°,V=0.5864(3)nm3,Z=1。配合物是由CuO6八面体通过共顶点连接构成一维链状结构,分子间氢键对分子间的结构稳定起到重要的作用;配合物存在弱的反铁磁性。One-dimensional coordination polymer [Cu（NPG）2（H2O）2]·CH3CH2OH was synthesized by solution method. Its structure was determined by single crystal X-ray diffraction analysis and further characterized by elemental analysis, IR spectra,TG. The results show that the title complex crystallizes in triclinic space group P-l, with a = 0.47674（12） nm,b = 0. 11319（3） nm,c = 0. 11614（3） nm,α = 106.468（4）°,β = 100.114（5）°,γ = 94.358（5） °,V = 0.5864（3） nm3,Z = 1. The title complex is built up from adjacent CuO6 octahedron by sharing corner to form one-dimensional chain. Hydrogen bonds between intermolecular play significant role in stabilization of the structure, and weak ferromagnetic interactions are observed in the complex.
