Abstract
A series of new twodimensional 2D lanthanideIII coordination polymers namely Ln2μ 2HTFMIDC3DMA4 · 2H2O n Ln = Pr 1 Nd 2 Sm 3 Eu 4 H3TFMIDC = 2trifluoromethyl1Himidazole45dicarboxylic acid DMA = NN′dimethylacetamide for type I and Ln2μ 2HTFMIDC3DMA2H2O2 · DMA n Ln = Eu 5 Gd 6 for type II have been successfully prepared under solvothermal conditions and structurally characterized for the first time Both two types of structures exhibit similar 2D honeycomblike networks which are constructed by the linkages of μ 2HTFMIDC2− bisbidentate bridging ligands and LnIII metal centers However slightly different ABAB stacking fashions of the 2D layers and distinctly different hydrogen bonding interactions between the neighboring 2D layers are observed in crystal structures of type I and type II which may be attributed to the lanthanide contraction effect Meanwhile the solidstate luminescent properties of 4 and 5 have been also investigatedThis work was financially supported by the National Natural Science Foundation of China Grant Nos 21473062 and 21571070 the Natural Science Foundation of Guangdong Province Grant No 2016A030310437 the Guangdong Provincial Science and Technology Project Grant Nos 2014A010101145 and 2016B090921005 the SCNU Foundation for Fostering Young Teachers Grant No 15KJ02 and the Undergraduates Innovating Experimentation Project of SCNU Grant No hx201602
