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.
