A novel heterometallic V2Ag2S4 thiocubane cluster was isolated from an assembly reaction system including (NH4)3VS4, Ag(PPh3)2NO3, OC4H8dtcNa and PhSNa in DMF. The title compound crystallizes in monoclinic space group C2/c with a = 2.0448(3) nm, b= 1.5086(2) nm, c= 1.7923(2) nm, β=109.32(1)°. The structure of the title compound was solved by using 1 500 (I>3σ(I)) unique reflections and refined to R = 0.068. The structural features indicate the formal oxidation state of V(IV) + Ag (I), and partial charge transfer from Ag(I) to V(IV). The actions of reactants used in the reaction are discussed and a supposed formation process of the V2Ag2S4 cluster is suggested.
