Abstract: In the organic/inorganic salt hydrate, 6C7H9ClN+·P6O186-·2H2O, the cyclohexaphosphate anion resides on an inversion centre. The asymmetric unit consists of three cations, one half-anion and a water molecule. In the crystal, the water molecules and the [P6O18]6- anions are linked by O-HO hydrogen bonds, generating infinite layers parallel to the ab plane. These layers are interconnected by the organic cations through N-HO hydrogen bonds.
