摘　　要：采用三(对-苯甲酸)甲烷(H3TCOPM)为配体,以Co为中心离子采用自组装的方法合成了配位聚合物{[Co3(TCOPM)2(H2O)2]·17H2O}n,利用单晶衍射仪,红外光谱,TG和元素分析对其进行了晶体结构的解析和表征。它属于单斜晶系,C2/c空间群,晶胞参数分别为a=2.9675(13)nm,b=1.3548(5)nm,c=1.8659(5)nm,α=90.00°,β=124.61(2)°,γ=90.00°,V=6.174(4)nm3,Mr=959.47,Z=4,Dc=1.187 g/cm3,μ=0.860 mm-1,F(000)=2268.0。结果表明,配位聚合物中H3TCOPM的三个羧酸全部和Co配位,形成三维结构,展现了一个具有tfd连接拓扑网络结构,其孔隙率为47.6%。Abstract： A novel coordination complex { [ Co3 （ TCOPM ） ： （ H2O ） 2 ]· 17 H2O / n （ H3 TCOPM = tris （ p- carboxyphenyl） methane） has been synthesized from H3TCOPM and Co2＋ by self-assembly method. The compound was characterized by elemental analysis, IR, TG and single-crystal X-ray diffraction analysis. Single-crystal X-ray analysis reveals that the title compound is crystallized in the monoclinic system, space group C2/c with a =2.9675（13） nm,b = 1. 3548（5） nm,c = 1. 8659（5） nm,α =90.00° ,β = 124.61 （2）°,γ =90.00°,V=6. 174（4） nm3,Mr =959. 47 ,Z =4 ,Dc =1. 187 g/cm3 ,/z =0.860 mm-1, F（000） = 2268.0. This result shows that three carboxylic acids of TCOPM3- are all coordinated with Co2＋ to form a 3 D structure with tfd topology type and a total potential solvent accessible void volume of 47.6% in this complex.
