Abstract

A new 3D Cd(II) coordination polymer, {[Cd₂(btc)(HL)(H₂O)]·3H₂O} _n (1) (H₂L= 3-(1H-pyrazol-4-yl)-5-(pyridin-2-yl)-1, 2, 4-triazole; H₃btc = 1,3,5-benzenetricarboxylic acid), has been synthesized by hydrothermal reaction of Cd(NO₃)₂·4H₂O, H₂L and H₃btc. It has been structurally characterized by element analysis, IR. X-ray single-crystal analysis was carried out for 1, which crystallizes in the monoclinic system, space group P2₁/n. The single X-ray diffraction reveals that compound 1 exhibits 3D framework structure. The luminescence properties of H₂L and compound 1 were investigated at room temperature in the solid state. Furthermore, the thermal decomposition behavior of the compound is characterized by thermogravimetric analyses.

摘要

新型3D Cd（II）配位聚合物{[Cd ₂（btc）（HL）（H ₂ O）]·3H ₂ O} _n（1）（H ₂ L = 3-（1H-吡唑-4-基）-5-（吡啶-2-基）-1，2，4-三唑; H ₃ btc = 1,3,5-苯三甲酸），是通过Cd（NO ₃）₂ ·4H _2的水热反应合成的O，H ₂ L和H ₃ btc。它已经通过元素分析IR进行了结构表征。对1进行X射线单晶分析，其在单斜晶系中结晶，空间群P2 ₁ / n 。单次X射线衍射表明化合物1具有3D骨架结构。在室温下以固态研究了H ₂ L和化合物1的发光性质。此外，化合物的热分解行为通过热重分析来表征。
