Abstract
Crystal growth in water between lanthanide ions and tetra-chloro-benzene-1,2-di-carboxylate (tcpa2−) led to 6 new coordination compounds with respective chemical formulas [Y(tcpa)(OH)(H2O)3]∞ (1), Nd4(tcpa)6(H2O)22·8H2O (2), [KLa(tcpa)2(H2O)10·H2O]∞ (3), [KLa(tcpa)2(H2O)5·2H2O]∞ (4), Y(tcpa)(Htcpa)(H2O)5 (5) and [KTb(tcpa)2(H2O)6·H2O]∞ (6). The crystal structures of these six compounds are described and compared with previously described crystal structures, focusing on the structural characteristics that are known for being key points for luminescence intensity. Trends induced by the presence of halogen atoms are identified.
