[μ-Butane-1,4-diylbis(di­phenyl­phos­phane)-κ(2) P:P′]bis­{[butane-1,4-diylbis(di­phenyl­phosphane)-κ(2) P,P′]copper(I)} bis­(hexa­fluorido­phosphate) diethyl ether disolvate

In the centrosymmetric dinuclear copper(I) complex cation of the title compound, [Cu(2)(C(28)H(28)P(2))(3)](PF(6))(2)·2C(4)H(10)O, the Cu(I) atom is bonded to three P atoms of two butane-1,4-diylbis(di­phenyl­phosphane) (dppb) ligands with a triangular coordination geometry. One of these P atoms belongs to a bridging dppb ligand [Cu—P = 2.2381 (5) Å] and two belong to a chelating dppb ligand [Cu—P = 2.2450 (6) and 2.2628 (5) Å]. The bridging dppb ligand lies on an inversion centre. In the crystal, the cation and the PF(6) (−) anion are linked by C—H⋯F inter­actions, forming a tape along [110]. The cation and the diethyl ether solvent mol­ecule are also linked by a C—H⋯O inter­action.
