title: Crystal structure of (μ-N-allyl-thio-urea-κ(2) S:S)bis-[μ-bis-(di-phenyl-phosphanyl)methane-κ(2) P:P']bis-[bromido-copper(I)] aceto-nitrile disolvate.
abstract: The reaction of cuprous bromide with a mixture of 1,1-bis-(di-phenyl-phosphan-yl)methane (dppm: C25H22P2) and N-allyl-thio-urea (ATU: C4H8N2S) in aceto-nitrile yielded the title solvated dinuclear complex, [Cu2Br2(C4H8N2S)(C25H22P2)2]·2C2H3N or [Cu2Br2(ATU)(dppm)2]·2CH3CN. Both Cu(+) ions adopt distorted tetra-hedral 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, intra-molecular C-H⋯S, C-H⋯π, N-H⋯Br and π-π stacking inter-actions are observed. In the crystal, the components are linked by N-H⋯Br and C-H⋯N hydrogen bonds and weak π-π stacking inter-actions, generating chains propagating in the [100] direction.
