Synthesis and structure of the palladium complexes [Ph3P(CH2)3PPh3][PdBr4], [Ph3P(CH2)3PPh3][Pd2Br6]·DMF, and [Ph3P(CH2)3PPh3][PdBr3(DMSO-S)]2

Аннотация

Complexes [Ph₃P(CH₂)₃PPh₃][PdBr₄] and [Ph₃P(CH₂)₃PPh₃][Pd₂Br₆]·DMF were synthesized by the reaction of dihydrogentetrabromopalladic acid with trimethylenebis(triphenylphosphonium) dibromide in water with subsequent recrystallization from N,N-dimethylformamide. The recrystallization of the first of them from dimethyl sulfoxide leads to the formation of the complex [Ph₃P(CH₂)₃PPh₃][PdBr₃(DMSO-S)]₂. Structure of the complexes was investigated by the X-ray diffraction (XRD) analysis.
