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

摘要

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-邻菲哕啉,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}n (2) (Hbtaa=1H-benzotriazole-1-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 in 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)]n 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.
