摘要:
The title compound, (C10H10N2S)[CuCl4], 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 Cu2+ ion. X-ray diffraction analysis reveals the presence of one 4,4'-thiodipyridinium cation, H(2)bps(2+), and one [CuCl4](2-) anion. The cations interact with the anions via N - H ... Cl hydrogen-bonding interactions to form a closed 'chair' conformation.
