Phosphine-substituted Cubane Clusters with the Mo3S4Ga Core

Research output: Contribution to journalArticlepeer-review


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).
