The ligand [{Me3SiC![[triple bond, length as m-dash]](http://www.rsc.org/images/entities/char_e002.gif)
CC(NDipp)2}Li(thf)3] (Dipp = 2,6-diisopropylphenyl) was used for salt metathesis reactions with [AuCl(tht)] (tht = tetrahydrothiophene) to obtain the dinuclear alkyne functionalized bisamidinate [{Me3SiCCC(NDipp)2}2Au2]. This compound serves as a building block for the polynuclear carbide bridged gold(I) amidinate complex [Au8{μ3-(η1:η2-CC)}2(Me3SiCCC(NDipp)2)4(tht)2], which is the first gold(I) complex with a μ3-η1:η2 carbide coordination. Both gold(I) compounds show distinct aurophilic interactions and are remarkably stable at ambient conditions. Photophysical investigations revealed intense luminescence with notable high quantum yields both in the solid state and in solution.

高度发光的八核金（I）碳化物簇
配体[{Me 3 SiCCC（NDipp）2 } Li（thf）3 ]（Dipp = 2,6-二异丙基苯基）用于与[AuCl（tht）]（tht =四氢噻吩）的盐复分解反应，以获得双核炔基官能化的双酰胺化物[{Me 3 SiC CC（NDipp）2 } 2 Au 2 ]。该化合物作为用于多核碳化物的构建块桥接金（我）脒基络合物[金8 {μ 3 - （η 1：η 2 -C C）} 2（ME 3的SiC CC（NDipp）2）4（THT）2 ]，它是第一金（我）复合物与μ 3 -η 1：η 2碳化物的协调。两种金（I）化合物均表现出不同的亲金相互作用，并且在环境条件下非常稳定。光物理研究表明，无论在固态还是在溶液中，都具有强烈的发光能力和显着的高量子产率。
