Crystal structure of (μ-N-allyl­thio­urea-κ(2) S:S)bis­[μ-bis­(di­phenyl­phosphanyl)methane-κ(2) P:P′]bis­[bromido­copper(I)] aceto­nitrile disolvate

The reaction of cuprous bromide with a mixture of 1,1-bis­(di­phenyl­phosphan­yl)methane (dppm: C(25)H(22)P(2)) and N-allyl­thio­urea (ATU: C(4)H(8)N(2)S) in aceto­nitrile yielded the title solvated dinuclear complex, [Cu(2)Br(2)(C(4)H(8)N(2)S)(C(25)H(22)P(2))(2)]·2C(2)H(3)N or [Cu(2)Br(2)(ATU)(dppm)(2)]·2CH(3)CN. Both Cu(+) ions adopt distorted tetra­hedral geometries, being coordinated by one terminal Br atom, one μ(2)-S atom of the bridging ATU ligand and two P atoms of the bridging dppm ligands. Within the complex, intra­molecular C—H⋯S, C—H⋯π, N—H⋯Br and π–π stacking inter­actions are observed. In the crystal, the components are linked by N—H⋯Br and C—H⋯N hydrogen bonds and weak π–π stacking inter­actions, generating chains propagating in the [100] direction.
