1.3.2. Synthesis, crystal structure and thermal stability property of a new terbium(III) coordination polymer based on 2,5-thiophenedicarboxylic acid

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.
