Abstract:	The reaction of cationic clusters Mo₃S₄(Dppet)₃X₃]X (I; Dppet = cis-1,2-bis(diphenylphosphino)ethylene; X = Cl, Br) with gallium metal in tetrahydrofuran (THF) affords cubane-like clusters Mo₃S₄(GaX)(Dppet)₃X₃] (IIa, X = Cl; IIb, X = Br). In the synthesis of IIb, the crystals of the cationic cluster Mo₃S₄(Dppet)₃Br₃](GaBr₄) (III) were isolated from the mother liquor. The structures of complexes IIa ? 1.5THF, IIb ? 1.5THF, III ? 1.625THF, and Mo₃S₄(Dppe)₃Br₃](GaBr₄) ? 2THF (IV ? 2THF; Dppe = 1,2-bis(diphenylphosphino)ethane) were established by X-ray diffraction (CIF files CCDC № 1851341–1851344).
