A ternary Cu–Sn–S cluster complex—(NBu4)[Cu19S28(SnPh)12(PEt2Ph)3]†
Abstract
Reaction of a mixture of CuCl, PhSnCl3 and PEt2Ph with S(SiMe3)2 in THF resulted initially in the unexpected synthesis of the ionic, mixed copper–tin sulfide cluster [Li(thf)4][Cu19S28(SnPh)12(PEt2Ph)3] in low yields. However, by adding NBu4Cl to the reaction solutions we were able to selectively synthesize the structurally similar cluster ion in (NBu4)[Cu19S28(SnPh)12(PEt2Ph)3].
