Starting from Mo(CO)6 and disulfanes R2P(S)-S-S-P(S)R2 the “trimetallic” tetranuclear clusters Mo2WCuS4I(R2PS2)43 (R = Et (a), Pr (b)) were obtained via the dinuclear compounds Mo2S4(R2PS2)21 and the trinuclear complexes Mo2WS4(R2PS2)42. The crystal structure of 3b shows a cubane-type core Mo2WCuS4. Both Mo atoms and the W atom are chelated by a dithiophosphinato ligand. One Mo and the W atom are bridged
