Crystal structure of bis[μ-1,4-bis(diphenylphosphanyl)butane-κ2P:P′]bis[(3,4,7,8-tetramethyl-1,10-phenanthroline-κ2N,N′)copper(I)] bis(hexafluoridophosphate) dichloromethane disolvate

The dication of the title compound, [Cu2(C28H28P2)2(C16H16N2)2](PF6)2·2CH2Cl2, 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
