Crystal structure of bis­[μ-1,4-bis­(di­phenyl­phos­phan­yl)butane-κ(2) P:P′]bis­[(3,4,7,8-tetra­methyl-1,10-phenanthroline-κ(2) N,N′)copper(I)] bis­(hexa­fluorido­phosphate) di­chloro­methane disolvate

The dication of the title compound, [Cu(2)(C(28)H(28)P(2))(2)(C(16)H(16)N(2))(2)](PF(6))(2)·2CH(2)Cl(2), has crystallographically imposed inversion symmetry. The copper(I) cation is coordinated in a distorted tetra­hedral geometry by two N atoms of a chelating 3,4,7,8-tetra­methyl-1,10-phenanthroline ligand and two P atoms of two bridging 1,4-bis­(di­phenyl­phosphan­yl)butane ligands, forming a 14-membered ring. An intra­molecular π–π inter­action stabilizes the conformation of the dication. In the crystal, dications are linked by π–π inter­actions involving adjacent phenanthroline rings, forming chains running parallel to [111]. Weak C—H⋯F hydrogen inter­actions are also observed.
