catena-Poly[μ₂-iodido-diiodidobis(μ₃-pyridine-2-thione-κ³S:S:S)(μ₂-pyridine-2-thione-κ²S:S)tricopper(I)]

In the title compound, [Cu₃I₃(C₅H₅NS)₃]_n, a polymeric structure is formed along [100] through bridging iodide and pyridine-2-thione ligands. The metal atoms are engaged in [Cu₃S₃] and [Cu₂S₂] rings sharing Cu—S edges, with the [Cu₂S₂] rings located about inversion centers. Cu^I atoms bridged by iodide ions exhibit the shortest Cu...Cu separation in the polymer [2.8590 (14) Å]. The three independent Cu^I atoms all display distorted tetra­hedral coordination geometries.
