The phosphoryl and carbonyl groups in the title compound, C15H20F2N3O2P, are anti with respect to each other (but the P- and C-groups are separated by another atom) and the P atom is in a tetrahedral coordination environment. Two C atoms in one of the pyrrolidinyl fragments are disordered over two sets of sites with occupancies of 0.746 (8) and 0.254 (8). The environments of the pyrrolidinyl N atoms show a slight deviation from planarity and none of the three N atoms is involved in any hydrogen bond as an acceptor. In the crystal, pairs of intermolecular N—H⋯O hydrogen bonds form inversion dimers.

2,6—F2C6H3C(O)NHP(O)Cl2 was prepared according to the literature method reported by Pourayoubi et al. (2010).
To a solution of 2,6—F2C6H3C(O)NHP(O)Cl2 (0.4 g, 1.46 mmol) in dry chloroform (30 ml), a solution of pyrrolidine (0.415 g, 5.84 mmol) in dry chloroform (10 ml) was added at 0 °C. After 4 h stirring, the solvent was removed and the product was washed with distilled water and recrystallized from a mixture of CH3OH/DMF (4:1) at room temperature. Single crystals of the title compound were obtained from this solution at room temperature.
All non-hydrogen atoms were refined anisotropically by Fourier full matrix least squares on F2. Hydrogen atom H1A was located from a Fourier difference map and allowed to refine with a N—H distance of 0.87 (1) Å and Uiso(H) = 1.2Ueq(N). All other hydrogen atoms were placed in geometrically idealized positions with C—H distances of 0.95 Å (aromatic) or 0.99 Å (CH2) and with Uiso(H) = 1.2Ueq(C). Carbon atoms C13 and C14 were disordered over two positions with approximate partial occupancies of 0.746 (8) and 0.254 (8). Hydrogen atoms on C12 and C15 were also treated using the above two parts model.

Experimental. IR (KBr, ν, cm-1): 3062 (NH), 2846, 1684, 1622, 1465, 1442, 1284, 1218, 1181, 1092, 1008, 876, 800, 768, 708, 586. |
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The patterns of hydrogen bonds and their strengths on phosphoric triamides containing a C(O)NHP(O) skeleton have been discussed (Toghraee et al., 2011; Pourayoubi et al., 2011). The structure determination of the title compound, C15H20F2N3O2P (Fig. 1), was performed as a continuation of work on this family of compounds in our laboratory.
The carbon atoms C13 and C14 in one of the pyrrolidinyl fragments are disordered over two sets of sites with occupancies of 0.746 (8) and 0.254 (8). The P═O and C═O groups are in anti positions with respect to each other. The P atom is in a distorted tetrahedral environment as has been noted for other phosphoric triamides (Sabbaghi et al., 2010). The nitrogen atoms show sp2 character, the average bond angles at the two tertiary N atoms being 117.8 and 118.7°, respectively. The P═O, C═O and P—N bond lengths, P—N—C bond angles and O—P—N—C torsion angles are within the expected values (Tarahhomi et al., 2011).
The P═O group and the N—H unit are syn with respect to one another. In the crystal, pairs of intermolecular N—H···O(P) hydrogen bonds (Table 1) form hydrogen-bonded dimers as R22(8) graph-set rings (Bernstein et al., 1995).
