摘 要：Four lanthanide coordination complexes, namely, [Ln（2,3-DClBA）3（5,5’-dmebipy）（H2O）]2（Ln=Sm（1）, Eu（2）, Dy（3）, Ho（4））; 2,3-DClBA=2,3-dichlorobenzoate; 5,5’-dmebipy=5,5’-dmethylbipyridine) were synthesized and characterized by elemental analysis, infrared spectroscopy and single crystal X-ray diffraction. Findings indicated that complex 3 was a dinuclear molecule, and the center Dy3+ was eight-coordinated. Each dinuclear units could be connected by H bond and halogen-halogen interactions. Luminescent property of complex 2 suggested the typical intense emissions of Eu3+ ions. Thermal analysis showed that the complexes decomposed in three steps: the coordination water was lost firstly then the neutral ligand 5,5’dmebipy was lost and lastly the 2,3-DClBA ligand was lost.
