The title compound, (C(10)H(10)N(2)S)[CuCl(4)], was obtained by the reaction of cupric chloride with pyridine-4-thiol in a mixture of acetonitrile and tetrahydrofuran, suggesting that the desulfurization and coupling reactions of pyridine-4-thiol occurred in the presence of the Cu(2+) ion. X-ray diffraction analysis reveals the presence of one 4,4'-thiodipyridinium cation, H(2)bps(2+), and one [CuCl(4)](2-) anion. The cations interact with the anions via N-H...Cl hydrogen-bonding interactions to form a closed 'chair' conformation.
