等摩尔的银与2，2 '-二硫代二苯甲酸（H（2）dtba）在超声条件下于50 °C反应，得到了一种新的阴离子十七核银（I）簇合物（NH（4））（17）[（μ（6）-S）@Ag（17）（mba）（16）]·2,2 H（2）O（1; H（2）mba = 2-巯基苯甲酸）.配合物1是一个不连续的簇合物，由位于壳层的mba配体和位于核层的μ（6）-S（2-）离子组成，表明H（2）dtba配体发生了原位S-S和S-C（sp（2））键断裂。这种新型团簇在室温下的固态下显示出中等的橙红色发射。
A novel anionic heptadecanuclear silver(I) cluster, (NH(4))(17)[(μ(6)-S)@Ag(17)(mba)(16)]·22H(2)O (1; H(2)mba = 2-mercaptobenzoic acid), was obtained by the reaction of equivalent molar silver oxide and 2,2'-dithiodibenzoic acid (H(2)dtba) under ultrasonic conditions at 50 °C. Complex 1 is a discrete cluster comprised of unexpected mba ligands on the shell and a μ(6)-S(2-) ion in the core, suggesting the occurrence of in situ S-S and S-C(sp(2)) bond cleavages of the H(2)dtba ligand. This novel cluster displays moderate orange-red emission in the solid state at room temperature.
