Über Antimon(V)-bromchloride und ihre Stabilisierung durch Elektronendonatoren

SbCl₃Br₂ may be stabilized by electron donors. Crystalline 1:1 adducts with diethyl ether, tetrahydrofurane, triphenylphosphine oxide and -sulphide were isolated. Their bonding properties, regarding the donor strengths, are discussed. The tetrahydrofurane adduct takes up three molecules of CCl₄ in the presences of CCl₄ · SbCl₃Br₂ · OP(C₆H₅)₃ is converted in introbenzene into SbCl₃Br₂ · O₂NC₆H₅ which, at room temperature, transforms in the course of 15 hours to heteropolar compounds of the general formula [SbCl_nBr_4?n · (O₂NC₆H₅)₂]+[SbCl_mBr_6?m]^?, with m + n = 6 and n = 1, 2, 3, 4.
