Bis[μ-bis(diphenylphosphino)methane-κ2P:P′]bis[(2,2′-bipyridine-κ2N,N′)copper(I)] bis(tetrafluoroborate)

The centrosymmetric title compound, [Cu2(C10H8N2)2(C25H22P2)2](BF4)2, consists of discrete dinuclear cations and tetrafluoroborate anions. The two CuI centers are bridged by the phosphine ligands to form an eight-membered ring. The CuI center exhibits a tetrahedral coordination as it is chelated by the N-heterocycle.
