中文摘要：
通过含2-噁唑啉基三角架配体1,3,5-三（2-噁唑啉基）苯（L）与三氟醋酸银反应合成了配合物[Ag4（L）2（CH3CN）2-（CF3CO2）4]n（1）,并利用元素分析、电喷雾质谱、X射线单晶衍射等方法对其进行了表征.晶体结构解析结果显示配合物1属三斜晶系,空间群P-1,a=0.83731（6）nm,b=1.22828（9）nm,c=1.33997（10）nm,α=102.9760（10）°,β=107.3050（10）°,γ=93.8600（10）°,Z=1,R=0.0365,wR2=0.0929.该配合物是由[Ag4（L）2（CF3CO2）2]^2＋笼状结构单元通过另外两个三氟醋酸根双桥连形成的一维链状结构.相邻的链间通过C-H…O氢键进一步扩展为二维网状结构.电喷雾质谱研究结果显示在实验条件下,溶液中配合物1是以聚合状态存在的.
英文摘要：
A new Ag（Ⅰ） complex [Ag4（L）2（CH3CN）2-（CF3CO2）4]n （1） was synthesized by the reaction of a 2-oxazolinyl-containing tripodal ligand 1,3,5-tris（2-oxazolinyl）benzene （L） with a silver（Ⅰ） trifluoroacetate and characterized by means of elemental analysis, electrospray mass （ES-MS） spectroscopy and single crystal X-ray diffraction. The results of the crystallographic analysis showed that the complex 1 is triclinic, with space group P-1, a=0.83731（6）nm,b=1.22828（9）nm,c=1.33997（10）nm,α=102.9760（10）°,β=107.3050（10）°,γ=93.8600（10）°,Z=1,R=0.0365,wR2=0.0929. The complex consists of [Ag4（L）2（CF3CO2）2]^2＋ cage-like subunits, which are further connected into 1D infinite chain by two bridging CF3COO^- anions. The 1D chains are further linked by C-H…O hydrogen bonds to form 2D network structure. The results of the ES-MS measurements suggested the polymeric structure of the complex in solution under the ES mass spectroscopy experimental conditions.
