摘要

合成一种由氢键连成的三维网状Cu(Ⅱ)配合物[Cu(bpy)2(ox)]·4H2O(bpy=2,2'-bipyridine,ox=oxalate ion)并进行了结构表征.重复单元[Cu(bpy)2(ox)]·4H2O通过由氢键连成的四边形和八边形的环交替连接形成三维网状结构.配合物的晶体结构属单斜晶系,空间群P2(1)/c,晶胞参数:a=0.948 3(5)nm,b=1.744 7(7)nm,c=1.613 1(7)nm,β=117.94(2)°,V=2.357 8(19)nm3,Z=4,F(000)=1108,μ=0.982,偏离因子R(int)=0.0625.%A hydrogen-bonded complex [Cu(bpy)2 (ox)]·4H2O has been synthesized. Its structure consists of a unique three-dimensional network in which [Cu (bpy)2 (ox)]·4H2O units are alternatively linked by tetracyclic and octacyclic rings. The complex crystallizes in monoclinic space group P2 (1)/c, Z = 4, with unit cell parameters of a=0. 948 3(5) nm, b=1.744 7(7)nm, c=1.613 1(7) nm, and β=117.94(2)°, V=2.3578(19) nm3, F(000)=1108, μ=0.982, R(int)=0.0625.
