一种由1,4,7-三氮杂环壬烷形成的三脚架配体及其与高氯酸钠组装的含[Na_4(ClO_4)_4]四面体晶体结构（英文）

A Tripodal Tris-tacn(tacn=1,4,7-Triazacyclononane) Ligand and Its Ability to Assemble a [Na_4(ClO_4)_4] Tetrahedron Cluster

合成了一种多齿的三脚架配体:三(2-(4,7-二甲磺酸基-1,4,7-三氮杂环壬烷基)甲基苄基)胺,即N(CH_2-o-C_6H_4-CH_2-tacnTs2)3(L),其中Ts=tosyl。它包含3个1,4,7-三氮杂环壬烷连接在三苄基胺的邻位。该配体在高氯酸钠存在情况下结晶,自组装得到4个钠离子形成的四面体结构晶体:[Na_4(L)(CH_3CN)(ClO_4)_4(H_2O)_3]_n。该晶体结构用X射线单晶衍射、粉末衍射、红外光谱和热重分析表征,并用紫外吸收和荧光对其光学性质进行表征。

A muhidentate tripodal ligand, tris（2-（（4,7-ditosyl-l,4,7-triazonan-l-yl）methyl）benzyl）amine, namely N （CH2-o-C6H4-CH2-tacnTs2）3 （L, Ts=tosyl）, which contains three triazacyclononane arms linked to the ortho positions of a tris（xylyl）amine scaffold, was synthesized. It stabilizes a [Na4（ClO4）4] tetrahedron cluster, which is rarely reported in the literature. The resulted complex has the formula of [Na4（Cs4H102N10O12S6）（CH3CN）（ClO4）4（H2O）3],. This tripodal tris-tacn complex has been characterized by single crystal X-ray diffraction, powder X-ray diffraction, infrared spectroscopy and thermal thermogravimetric analysis. UV-visible absorption spectrum and fluorescence spectrum were measured to characterize the optical properties of the complex.
