摘要: 本文利用水热合成方法,将稀土氧化物与邻苯二乙酸(H2pda)反应得到了2个新颖的稀土配位聚合物{[Ln2(pda)3(H2O)2]·2H2O}n(Ln=Nd(1),La(2))。测定了它们的晶体结构,并进行了X-射线单晶衍射、红外光谱、荧光光谱和热重分析等性质的表征。晶体结构测定表明这2个化合物为异质同晶化合物。属单斜晶系,C2/c空间群。晶体学参数分别为配合物1：a=2.62906(18)nm,b=1.61172(11)nm,c=0.78327(5)nm,β=93.173(5)°,V=3.3139(4)nm3,Z=4,F(000)=1840,μ=3.173mm-1,Dc=1.878g·cm-3,R1=0.0226,wR2=0.0609；配合物2：a=2.6271(14)nm,b=1.6149(8)nm,c=0.7966(4)nm,β=92.850(9)°,V=3.375(3)nm3,Z=4,F(000)=1816,μ=2.570mm-1,Dc=1.823g·cm-3,R1=0.0466,wR2=0.1416。化合物中邻苯二乙酸配体连接相邻的稀土金属离子,形成复杂的具有stp拓朴构型的三维网络结构。
