摘要

The reaction of cuprous bromide with a mixture of 1,1-bis­(di­phenyl­phosphan­yl)methane (dppm: C25H22P2) and N-allyl­thio­urea (ATU: C4H8N2S) in aceto­nitrile yielded the title solvated dinuclear complex, [Cu2Br2(C4H8N2S)(C25H22P2)2]·2C2H3N or [Cu2Br2(ATU)(dppm)2]·2CH3CN. Both Cu+ ions adopt distorted tetra­hedral geometries, being coordinated by one terminal Br atom, one μ2-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.
