Auxiliary Ligand-tuned Structural Variation of Cd(II) Coordination Polymers: Synthesis, Crystal Structures and Luminescent Properties
摘要:
Two new Cd(Ⅱ) coordination polymers,[Cd(PT)(1,4-BDC)0.5]n (1) and [Cd(PT) (1,3-BDC)0.5]n (2) (HPT=3-(pyridin-2-yl)-1,2,4-triazole, 1,4-H2BDC=1,4-benzenedicarboxylic acid, 1,3-H2BDC=1,3-benzenedicarboxylic acid), have been hydrothermally synthesized and structurally characterized by single-crystal X-ray diffraction as well as elemental analysis and IR. Complexes 1 and 2 are both three-dimensional coordination polymers with two-dimensional sheet structures bridged by the deprotonated carboxylate ligands. In 1, 1,4-BDC2- bridges the layered network to generate a quadrangular framework, and 2 owns a sexangular framework, which was caused by the different steric hindrance between 1,4-BDC2- and 1,3-BDC2-. Their thermal stabilities and photoluminescent properties have been also investigated.
