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％.
