Abstract: The dinuclear cation of the title complex, [Cu₂(C₂₅H₂₂P₂)₂(C₁₀H₈N₂)₂](BF₄)₂·2C₄H₁₀O, lies on a centre of inversion. Each Cu^I atom is coordinated by 2,2'-bipyridine (bpy) and bis(diphenylphosphino)methane (dppm) ligands, and has a distorted tetrahedral coordination geometry. The distance between the two Cu^I atoms separated by two dppm bridging ligands is 4.671 (3) Å. The solvent molecule and anion are each disordered over two positions; the site occupancy factor ratios are ca 0.56:0.44 and 0.6:0.4, respectively
