摘要：
A series of lanthanide coordination polymers, namely {[Ln(HL)(H2O)(2)].H2O}n (Ln = Ce(1), Pr(2), Nd(3), Eu(4) and Tb(5); H4L = 1,1'-(propane-1,3-diyl)bis(1H-imidazole-4,5-dicarboxylic acid)) have been synthesized under hydrothermal conditions and characterized by infrared spectroscopy, element analysis, single-crystal X-ray diffraction, powder X-ray diffraction and thermogravimetric analyses. These isostructural complexes exhibit 3D framework with a sra topology built by HL3- anions mu(4)-bridging metal ions through two IDC groups it different coordination modes. The luminescent property of complexes containing Eu(III) and Tb(III) have also been investigated in detail.
