metal-organic compounds
The reaction of copper(II) chloride with pyridine-2-thiol affords the title complex, [Cu2Cl2(C10H8N2S)2]n, in which two pyridine-2-thiol molecules have reacted to give a betain ligand and the copper centre has undergone reduction. The copper metal centre exhibits a distorted tetrahedral coordination geometry with bridging chloride and 1-(2-pyridyl)pyridinium-2-thiolate ligands, giving centrosymmetric dimers further linked into a polymeric chain.
