μ-Chlorido-μ-chlorido-(μ-pyrrolidine-1-carbo-dithio-ato-κ:,':')tris-[(tri-ethyl-phosphane-κ)copper(I)]: crystal structure and Hirshfeld surface analysis.

The title trinuclear compound, [Cu(CHNS)Cl(CHP)], has the di-thio-carbamate ligand symmetrically chelating one Cu atom and each of the S atoms bridging to another Cu atom. Both chloride ligands are bridging, one being μ- and the other μ-bridging. Each EtP ligand occupies a terminal position. Two of the Cu atoms exist within ClPS donor sets and the third is based on a ClPS donor set, with each coordination geometry based on a distorted tetra-hedron. The constituents defining the core of the mol-ecule, CuClS, occupy seven corners of a distorted cube. In the crystal, linear supra-molecular chains along the axis are formed phosphane-methyl-ene-C-H⋯Cl and pyrrolidine-methyl-ene-C-H⋯π(chelate) inter-actions, and these chains pack without directional inter-actions between them. An analysis of the Hirshfeld surface points to the predominance of H atoms at the surface, contributing 86.6% to the surface, and also highlights the presence of C-H⋯π(chelate) inter-actions.
