In the phosphoric triamide molecule of the title compound, C6H14N+·C2H3O2−·C18H36N3OP, the P atom displays a distorted tetrahedral geometry and the cyclohexyl rings adopt chair conformations with the NH groups in equatorial positions. In the crystal, the cations, anions and phosphoric triamide molecules are linked via N—H⋯O hydrogen bonds into a two-dimensional array parallel to the bc plane. The O atom of the P(O) group acts as a double-hydrogen-bond acceptor.
