In the organic/inorganic salt hydrate, 6C7H9ClN +·P6O18 6-·2H 2O, 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-H.O hydrogen bonds, generating infinite layers parallel to the ab plane. These layers are interconnected by the organic cations through N-H.O hydrogen bonds.

In the crystal structure of the title compound, 4C5H 6ClN2 +·H2P6O 18 4-, the [H2P6O18] 4- anions are interconnected by O - H⋯O hydrogen bonds, leading to the formation of infinite ribbons extending along the a-axis direction. These ribbons are linked to the organic cations, via N - H⋯O and C - H⋯O hydrogen bonds, into a three-dimensional network. The six P atoms of the [H2P6O18]4- anion form a chair conformation. The complete cyclohexaphosphate anion is generated by inversion symmetry.
