{μ-N,N,N′,N′-Tetrakis[(diphenylphosphanyl)methyl]benzene-1,4-diamine}bis[(2,2′-bipyridyl)copper(I)] bis(tetrafluoridoborate)

Abstract

In the title compound, [Cu2(C10H8N2)2(C58H52N2P4)](BF4)2, the dinuclear cation lies on an inversion centre. The CuI atom is coordinated by two N atoms from a 2,2′-bipyridine ligand and two P atoms from an N,N,N′,N′-tetrakis[(diphenylphosphanyl)methyl]benzene-1,4-diamine ligand in a distorted tetrahedral geometry. In the crystal, intermolecular C—H...F hydrogen bonds link the ions into layers parallel to [overline{1}01]. π–π interactions [centroid–centroid distance = 3.668 (4) Å] are also observed. One F atom of the anion is disordered over two orientations with a refined occupancy ratio of 0.675 (13):0.325 (13).
