A homoleptic copper(I) tetramer, [Cu(PhTt)]4 1, is synthesized using phenyltris[(methylthio)methyl)]borate, PhTt–; X-ray analysis shows the four copper ions are nearly coplanar and each resides in an approximately tetrahedral environment; although 1 is stable towards O2, H2O and CO, it reacts with PPh3, pyridine, or [NEt4]SPh to yield the corresponding monomer, [Cu(PhTt)L](L = PPh3 2, py 3, [NEt4]SPh 4).

铜(I)四聚体 [Cu(PhTt)]4 1;X 射线分析表明,四个
铜离子几乎共面,每个
铜离子都处于近似四面体的环境中;虽然 1 对 O2、
H2O 和 CO 稳定,但它会与 PPh3、
吡啶或 [NEt4]
SPh 反应,生成相应的单体 [Cu(PhTt)L](L = PPh3 2、py 3、[NEt4]
SPh 4)。
