1,4,7-Triazacyclononane (TACN) has been used for the first time to support Au(i)M [M = Tl(i), Ag(i)] metallophilic interactions in the formation of heteronuclear gold(i) complexes having luminescence properties. The compounds {[{Au(C6Cl5)2}Tl(TACN)]2}n (1), [{Au(C6F5)2}Tl(TACN)] (2), [{Au(C6Cl5)2}Ag(TACN)] (3), and [{Au(C6F5)2}{Ag(TACN)}2Au(C6F5)2] (4) have been synthesized by reacting TACN and the polymeric starting organometallic gold(i) compounds [{Au(C6X5)2}M]n (M = Ag(i), Tl(i); X = Cl, F) in a 1 : 1 molar ratio, in THF. 1, 3 and 4 have also been structurally characterized and their optical properties explained on the basis of their structural features with the support of TD-DFT calculations.
1,4,7-三氮杂环壬烷（TACN）首次用于在具有发光性质的异核金（I）配合物形成过程中支持金（I）-M [M = 铊（I），银（I）]亲金属相互作用。通过使TACN与聚合起始有机金属金（I）化合物[{Au（C6X5）2}M]n（M = 银（I），铊（I）；X = Cl，F）以1:1摩尔比在四氢呋喃中反应，合成了化合物{[{Au（C6Cl5）2}Tl（TACN）]2}n（1）、[{Au（C6F5）2}Tl（TACN）]（2）、[{Au（C6Cl5）2}Ag（TACN）]（3）和[{Au（C6F5）2}{Ag（TACN）}2Au（C6F5）2]（4）。还对1、3和4进行了结构表征，并在含时密度泛函理论计算的支持下，根据其结构特征解释了它们的光学性质。
