Bis(tetraphenylphosphonium) tetrachloridocobaltate(II)

Abstract

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