两个由1H-苯并三氮唑-1-乙酸构筑的镉、银配合物的合成及晶体结构(英文)

Synthesis and Crystal Structure of Two Complexes of Cadmium, Silver Assembled by 1H-Benzotriazole-1-acetic Acid

合成了2个配位聚合物{[Cd(btaa)(phen)(CH3COO)].H2O}n(1)和{[Ag2(btaa)(4,4-bpy)2](NO3).2H2O}n(2)(Hbtaa=1H-苯并三氮唑-1-乙酸,phen=1,10-邻菲啰啉,4,4-bpy=4,4-联吡啶),采用单晶X-射线、红外光谱、元素分析和热重分析对配合物进行了表征。配合物1中的镉离子通过1H-苯并三氮唑-1-乙酸根桥连成一维螺旋链状结构。在配合物2中,银离子被4,4-联吡啶连接成一维链状结构,这些一维链通过1H-苯并三氮唑-1-乙酸根桥连以及Ag...Ag作用和π-π堆积连接成一维梯子状结构。此外,还研究了配合物1的荧光性质。

Two coordination polymers {[Cd （btaa） （phen） （CH3COO）] ·H2O}n （1）, and {[Ag2（btaa） （4,4-bpy）2] （NO3） · 2H2O}, （2） （Hbtaa=1H-benzotriazole-l-acetic acid, phen=1,10-phenanthroline, 4,4-bpy=4,4-bipyridine） were prepared and characterized by IR spectrum, elemental analysis, TG and single-crystal X-ray analyses. The cadmium ion m complex 1 is linked by btaa ligands into one-dimensional helical chain coordination polymer motif. A ladder type of structure was observed in 2 in which two of the [Ag（4,4＇-bpy）], linear chains are bridged by btaa ligands and paired by Ag…Ag interactions and π-π stacking interactions. Moreover, the luminescent property of complex 1 has been investigated in the solid state. CCDC： 901938, 1; 901939, 2.
