μ-2,2'-Bipyrimidine-κ(4)N(1),N(1'):N(3),N(3')-bis-[iodido(triphenyl-phosphane-κP)copper(I)] dimethyl-formamide disolvate.

In the title binuclear centrosymmetric complex, [Cu(2)I(2)(C(8)H(6)N(4))(C(18)H(15)P)(2)]·2C(3)H(7)NO, the bis-bidentate 2,2'-bipyrimidine ligand bridges two copper(I) ions, each additionally bound to an iodide anion and a triphenyl-phosphane ligand in a distorted tetra-hedral N(2)IP geometry. The complex mol-ecules pack in columns parallel to [100] generating cavities occupied by dimethyl-formamide solvent mol-ecules. Weak C-H⋯I hydrogen-bonding inter-actions help to stabilize the crystal packing.
