Crystal structure of (μ-N-allylthiourea-κ²S:S)bis[μ-bis(diphenylphosphanyl)methane-κ²P:P′]bis[bromidocopper(I)] acetonitrile disolvate

Abstract

In the solvated dinuclear complex [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.
