Crystal structure of benzyl­tri­phenyl­phospho­nium chloride monohydrate

The title compound, Ph(3)(PhCH(2))P(+)·Cl(−)·H(2)O, was obtained unintentionally as the product of an attempted synthesis of a silver di­thio­carbamate complex using benzyl­tri­phenyl­phospho­nium as the counter-ion. The asymmetric unit consists of a phospho­nium cation and a chloride anion, and a water mol­ecule of crystallization. In the crystal, the chloride ion is linked to the water mol­ecule by an O—H⋯Cl hydrogen bond. The three units are further linked via C—H⋯Cl and C—H⋯O hydrogen bonds and C—H⋯ π inter­actions, forming a three-dimensional structure.
