The atomic arrangement of the title compound, 3C(6)H(18)N(2)(2+).P6O18
6-.6H(2)O, is described as a stacking of P6O18 groups and organic enti
ties. The stability of such an arrangement results from a network of w
eak hydrogen bonds [N(O)-H ... O] connecting organic groups and water
molecules to the external O atoms of the ring anions.
