| 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。 |

| Abstract: 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. |
