μ-Butane-14-diylbis(di­phenyl­phos­phane)-κ2P:P′bis­{butane-14-diylbis(di­phenyl­phosphane)-κ2PP′copper(I)} bis­(hexa­fluorido­phosphate) diethyl ether disolvate

摘要

In the centrosymmetric dinuclear copper(I) complex cation of the title compound, [Cu2(C28H28P2)3](PF6)2·2C4H10O, 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 PF6 ⁻ 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.
