在水热反应条件下,设计合成了一种新型三维配位聚合物[La(C5H4NCOO)3(H2O)2]n的单晶体,对其进行了元素分析、热重分析、红外光谱表征、X射线单晶衍射测定.该配位聚合物属单斜晶系,P2(1)/c空间群,晶胞参数为a=0.9747(4)nm,b=1.9904(7)nm,c=1.1613(4)nm,α=90°,β=111.761(6)°,γ=90°,V=2.0925(13)nm3,Z=4,dc=1.718g/cm3,μ=2.090mm-1,F(000)＝1064,R1=0.0374, wR2=0.0683.X射线衍射结果显示La3+离子之间以4-氰基吡啶的羧基为桥形成一维链状结构,通过4-氰基吡啶的吡啶基与配位的水分子之间的氢键形成三维的网络结构.热重分析表明该配位聚合物在230℃下稳定.
