In the title compound, C16H17Cl3N3O2P, the P—N bonds in the P(O)[NH(2—CH3)C6H4]2 unit [1.623 (4) and 1.637 (3) Å] are shorter than the P—N bond in the C(O)NHP(O) fragment [1.704 (3) Å]. The phosphoryl and carbonyl groups are anti with respect to each other and the P atom has a distorted tetrahedral configuration. In the crystal, adjacent molecules are linked via N—H⋯O(P) and N—H⋯O(C) hydrogen bonds into an extended chain parallel to [101].

CCl3C(O)NHP(O)Cl2 was synthesized from the reaction between phosphorus pentachloride (16.7 mmol) and 2,2,2-trichloroacetamide (16.7 mmol) in dry CCl4 at 358 K (3 h) and then the treatment of formic acid 85% (16.7 mmol) at ice bath temperature. To a solution of CCl3C(O)NHP(O)Cl2 (1.79 mmol) in CHCl3, a solution of o-toluidine (7.16 mmol) in CHCl3 was added dropwise at 273 K. After 4 h of stirring, the solvent was evaporated at room temperature. The solid was washed with distilled water. Single crystals were obtained from a mixture of CH3OH/CH3CN after slow evaporation at room temperature.
H-atoms were included in geometrically idealized positions with N—H = 0.98 Å and C—H = 0.95 and 0.98Å for aryl and methyl type H-atoms, respectively, and were included in the
with Uiso(H) = 1.2Ueq(C/N).The
of the title compound, P(O)[NHC(O)CCl3][NHC6H4(2-CH3)]2 (Fig. 1), was performed in continuing of works on the synthesis and structural investigation of new phosphoramidate compounds having a C(O)NHP(O) skeleton (Toghraee et al., 2011; Pourayoubi, Tarahhomi et al., 2011).The phosphoryl and the carbonyl groups adopt the anti positions with respect to each other. The P atom has a distorted tetrahedral conformation. The bond angles around the P atom are in the range of 102.06 (17)° to 117.28 (17)°. As expected, the P1—N2 (1.623 (4) Å) and P1—N3 (1.637 (3) Å) bonds are shorter than the P1—N1 (1.704 (3) Å) bond. The P═O and C═O bond lengths and the P—N—C bond angles are standard for this category of compounds (Pourayoubi, Fadaei & Parvez, 2011).

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 the title compound, P(O)[NHC(O)CCl3][NHC6H4(2-CH3)]2 (Fig. 1), was performed in continuing of works on the synthesis and structural investigation of new phosphoramidate compounds having a C(O)NHP(O) skeleton (Toghraee et al., 2011; Pourayoubi, Tarahhomi et al., 2011).
The phosphoryl and the carbonyl groups adopt the anti positions with respect to each other. The P atom has a distorted tetrahedral conformation. The bond angles around the P atom are in the range of 102.06 (17)° to 117.28 (17)°. As expected, the P1—N2 (1.623 (4) Å) and P1—N3 (1.637 (3) Å) bonds are shorter than the P1—N1 (1.704 (3) Å) bond. The P═O and C═O bond lengths and the P—N—C bond angles are standard for this category of compounds (Pourayoubi, Fadaei & Parvez, 2011).
In the crystal structure, adjacent molecules are linked via NC(O)NHP(O)—H···O(P) and N—H···O(C) hydrogen bonds, into an extended chain parallel to [101], Table 1 and Fig. 2.
