ABSTRACT
In the crystal structure of the title compound, 4C5H6ClN2 (+)·H2P6O18 (4-), the [H2P6O18](4-) anions are interconnected by O-Hâ¯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-Hâ¯O and C-Hâ¯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.
ABSTRACT
In the organic/inorganic salt hydrate, 6C7H9ClN(+)·P6O18 (6-)·2H2O, the cyclo-hexa-phosphate anion resides on an inversion centre. The asymmetric unit consists of three cations, one half-anion and a water mol-ecule. In the crystal, the water mol-ecules and the [P6O18](6-) anions are linked by O-Hâ¯O hydrogen bonds, generating infinite layers parallel to the ab plane. These layers are inter-connected by the organic cations through N-Hâ¯O hydrogen bonds.
