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—HO 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.

A second monoclinic polymorph of the title molecule, C15H21FN3O4P, is reported in the space group P21/n and compared to the previously reported C2/c space group [Gholivand et al. (2006). Polyhedron, 25, 711–721]. The asymmetric unit of the title compound consists of two independent molecules. The P atoms adopt a distorted tetrahedral environment. In the C(O)NHP(O) fragment, the P=O and the N—H groups are in a syn conformation with respect to each other and in the crystal, intermolecular N—HO=P hydrogen bonds form dimeric aggregates.

The P atom in the title molecule, C15H20F2N3O2P, is in a distorted tetrahedral P(O)(N)(N)2 environment. The phosphoryl group and the NH unit adopt a syn orientation with respect to each other. An F atom at position 2 and an H atom at position 6 are found to occupy similar sites in a 0.70:0.30 ratio and were refined with fixed occupancies. The pyrrolidin-1-yl rings are disordered over two sets of sites, with site occupancies of 0.566 (6) and 0.434 (6), and were refined using a two-part model. In the crystal, hydrogen-bonded dimers linked by pairs of N—HO(P) hydrogen bonds generate an R22(8) ring motif.

In the title molecule, C16H17ClF2N3O2P, the N—H unit of the C(=O)NHP(=O) fragment adopts a syn orientation with respect to the P=O group. The two F atoms and the Cl atom of the ClF2C group are disordered over two sets of sites with refined occupancies of 0.605 (6) and 0.395 (6). In the crystal, molecules are linked via N—HO=C hydrogen bonds and the (N—H)(N—H)O=P group into chains along [010].
