Abstract

Abstract: A new coordination polymer [Tb2L2(Ox)(H2O)4]n·nH2O (H2L = 2,5-thiophenedicarboxylic acid, H2Ox = Oxalicacid) has been synthesized under hydrothermal reaction andcharacterized by single crystal X-ray diffraction analysis, IRspectra, and thermogravimetric analyses. The two Tb atoms areeight-coordinated in a distorted dodecahedron geometry for Tb1and in a distorted bicapped trigonal prism geometry for Tb2.The structure possesses a 3D (3,8)-connected topology net withTb2(COO)2O12 SBUs and L2–, Ox2– ligands. The thermogravimetricproperty of 1 has been investigated.Supporting information: CIF file.

1.3.2. 基于2,5-噻吩二羧酸的新型铽(III)配位聚合物的合成、晶体结构和热稳定性

摘要:水热合成了一种新型配位聚合物[Tb2L2(Ox)(H2O)4]n·nH2O (H2L = 2,5-噻吩二羧酸，H2Ox =草酸)，并用单晶x射线衍射、红外光谱和热重分析对其进行了表征。两个Tb原子在tb1的畸变十二面体几何结构中是八配位的，在Tb2的畸变双头三角棱镜几何结构中是八配位的。该结构具有由tb2 (COO)2O12 SBUs和L2 -， Ox2 -配体组成的三维(3,8)连接拓扑网络。研究了1的热重性质。支持信息:CIF文件。
