A second monoclinic polymorph of the title molecule, C15H21FN3O4P, is reported in the P21/n and compared to the previously reported C2/c [Gholivand et al. (2006). Polyhedron, 25, 711–721]. The 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—H⋯O=P hydrogen bonds form dimeric aggregates.

4-F—C6H4C(O)NHP(O)Cl2 was prepared according to the literature method reported by Gholivand et al. (2006).
To a solution of 4-F—C6H4C(O)NHP(O)Cl2 (0.723 g, 2.825 mmol) in dry acetonitrile (25 ml), a solution of morpholine (0.984 g, 11.300 mmol) in dry acetonitrile (5 ml) was added at 273 K. After 4 h stirring, the solvent was removed and the product was washed with distilled water and the resulting precipitate of 4-F—C6H4C(O)NHP(O)(NC4H8O)2 was collected. Single crystals were obtained in a try on a reaction between 4-F—C6H4C(O)NHP(O)(NC4H8O)2 and Sn(CH3)2Cl2 in CH3OH under reflux, followed by slow evaporation of the filtered solution at room temperature.
All non-hydrogen atoms were refined anisotropically by full matrix least squares on F2. Hydrogen atoms H1N and H4N were found from a Fourier difference map and their N—H distances were fixed at 0.87 (2) Å and were allowed to refine isotropically with 1.20 Ueq of parent N atoms. All other hydrogen atoms were placed in calculated positions and treated as riding on their parent C atoms with distances C—H = 0.990 Å (CH2) and 1.00 Å (CH) with 1.20Ueq of their parent C atoms.
The β of 106.93 (3)° while those of P21/n at 100 K have smaller cell dimensions indicative of a possible phase change.
of a monoclinic polymorph of the title molecule, [4-F—C6H4C(O)NH]P(O)[NC4H8O]2 (Fig. 1), in a C2/c with Z = 8 was investigated in ambient temperature, Gholivand et al. (2006). Here, we report on a second monoclinic polymorph in a P21/n with Z = 8. Cell parameters for both polymorphs exhibit similar dimensions. The C2/c structure at 293 K has cell parameters of 15.732 (3), 10.740 (2), 21.553 (4) Å withThe
consists of two independent molecules; in each molecule, the phosphoryl group adopts a syn orientation with respect to the N—H unit. In the first monoclinic modification of this compound (Gholivand et al., 2006), the is composed of one molecule involving disorder in one morpholin-4-yl moiety. The P atom is in a distorted tetrahedral environment as has been noted for other (Pourayoubi, Nečas & Negari, 2012 and Pourayoubi, Tarahhomi et al., 2012).The P═O, C═O and P—N bond lengths and P—N—C bond angles are within the expected values (Gholivand et al., 2006).
In the crystal, two different intermolecular N—H···O(P) hydrogen bonds make dimeric aggregates. So, each hydrogen-bonded dimer is built of two symmetrically independent molecules (Fig. 2).

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 structure determination of a monoclinic polymorph of the title molecule, [4-F—C6H4C(O)NH]P(O)[NC4H8O]2 (Fig. 1), in a C2/c space group with Z = 8 was investigated in ambient temperature, Gholivand et al. (2006). Here, we report on a second monoclinic polymorph in a space group P21/n with Z = 8. Cell parameters for both polymorphs exhibit similar dimensions. The C2/c structure at 293 K has cell parameters of 15.732 (3), 10.740 (2), 21.553 (4) Å with β of 106.93 (3)° while those of P21/n at 100 K have smaller cell dimensions indicative of a possible phase change.
The asymmetric unit consists of two independent molecules; in each molecule, the phosphoryl group adopts a syn orientation with respect to the N—H unit. In the first monoclinic modification of this compound (Gholivand et al., 2006), the asymmetric unit is composed of one molecule involving disorder in one morpholin-4-yl moiety. The P atom is in a distorted tetrahedral environment as has been noted for other phosphoramides (Pourayoubi, Nečas & Negari, 2012 and Pourayoubi, Tarahhomi et al., 2012).
The P═O, C═O and P—N bond lengths and P—N—C bond angles are within the expected values (Gholivand et al., 2006).
In the crystal, two different intermolecular N—H···O(P) hydrogen bonds make dimeric aggregates. So, each hydrogen-bonded dimer is built of two symmetrically independent molecules (Fig. 2).
