title: Crystal structure of bis-[μ-1,4-bis-(di-phenyl-phos-phan-yl)butane-κ2P:P']bis-[(3,4,7,8-tetra-methyl-1,10-phenanthroline-κ2N,N')copper(I)] bis-(hexa-fluorido-phosphate) di-chloro-methane disolvate.
abstract: 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 tetra-hedral geometry by two N atoms of a chelating 3,4,7,8-tetra-methyl-1,10-phenanthroline ligand and two P atoms of two bridging 1,4-bis-(di-phenyl-phosphan-yl)butane ligands, forming a 14-membered ring. An intra-molecular π-π inter-action stabilizes the conformation of the dication. In the crystal, dications are linked by π-π inter-actions involving adjacent phenanthroline rings, forming chains running parallel to [111]. Weak C-H⋯F hydrogen inter-actions are also observed.
