Synthesis and crystal structure of a novel pentaconta-nuclear silver anionic cluster complex [HNEt3]4[Ag50S7(SC6H4But-4)40]·2CS2·6C3H6O

A silver 4-tert-butylthiophenolate complex generated in situ reacted with CS2 in acetone to give an anionic cluster [Ag50S7(SC6H4But-4)40]4−, the core of which consists of fifty silver atoms and forty-seven sulfur atoms, shaped like a discus with a diameter of ca. 2.0 nm.
