用中温溶剂热方法合成了一种未见报道的二维配位聚合物[Co3(1,4-BDC)3(DMA)(H2O)],通过X射线衍射技术确定了其晶体结构.在该配合物中,6个1,4-对苯二甲酸(1,4-H2BDC)配体连接着Co三聚体向各个方向延伸,形成了层状结构.结果表明:该化合物属于单斜晶系,P21/n空间群;晶胞参数a=1.5601(3)nm,b=0.97685(19)nm,c=1.5926(3)nm,α=90°,β=109.819(4)°,γ=90°,V=2.2834(8)nm3,Z=2,R1=0.0692,wR2=0.1164.
A novel two-dimensional coordination polymer constructed by 1, 4-benzenedicarboxylate and cobalt ion was synthesized by solvothermal technique. The crystal structure of the compound was discussed in detail. The compound crystallized in the monoclinic, space group P21/n with a = 1. 560 1 (3) nm, b = 0.976 85(19) nm, c=1.592 6(3) nm,α= 90°,β= 109.819(4)°,γ=90°, V=2.283 4(8) nm^3,Z=2, R1=0.069 2,wR2=0. 116 4
