Hexa­kis­(3-chloro-2-methyl­anilinium) cyclo­hexa­phosphate dihydrate

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—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.

Tetra­kis(2-amino-5-chloro­pyridinium) di­hydrogen cyclo­hexa­phosphate

In the crystal structure of the title compound, 4C₅H₆ClN₂⁺·H₂P₆O₁₈⁴⁻, 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.
