The title compound, (C24H20P)2[CoCl4], was prepared under hydrothermal conditions. In the crystal, the tetraphenylphosphonium cations are linked by pairs of weak C—Hπ interactions into supramolecular dimers; the CoII cations lie on twofold rotation axes and the tetrahedral [CoCl4]2− anions are linked with the tetraphenylphosphonium cations via weak C—HCl hydrogen bonds.
