title: catena-Poly[[copper(I)-bis[μ-bis(di-phenyl-phos-phino)methane-κP:P']-copper(I)-μ-2,2'-bipyridine-κN:N'] bis(tetra-fluorido-borate) dichloromethane 2.5-solvate].
abstract: The title complex, {[Cu(2)(C(10)H(8)N(2))(C(25)H(22)P(2))(2)](BF(4))(2)·2.5CH(2)Cl(2)}(n), contains chains of Cu(I) centres bridged alternately by two (diphenyl-phosphino)methane (dppm) and 4,4'-bipyridine (bpy) ligands. Each Cu(I) atom is coordinated by one N atom of 4,4'-bipyridine (bpy) and two P atoms of two (diphenyl-phosphino)methane (dppm) ligand, and has a trigonal-planar coordination geometry. There is an inversion centre midway between each pair of adjacent Cu atoms. The distance of two Cu(I) atoms separated by two (diphenyl-phosphino)methane bridging ligands is 3.732 (3) Å, and 4,4'-bipyridine 11.138 (5) Å.
