N,N,N′,N′-Tetra­ethyl-N′′-(2-fluoro­benzo­yl)phospho­ric triamide

In the title compound, C(15)H(25)FN(3)O(2)P, the phosphoryl group is in an anti and syn orientation to the C=O and N—H groups, respectively. The P atom is in a distorted tetra­hedral environment. One of the ethyl groups is disordered over two sets of sites with refined occupancies of 0.755 (6) and 0.245 (6). In addition, the F atom was refined as disordered with occupancies fixed at 0.9 and 0.1. This disorder corresponds to a rotation of approximately 180° of the fluoro­benzene ring about its connecting C—C bond. In the crystal, pairs of inter­molecular N—H⋯O(=P) hydrogen bonds form centrosymmetric dimers.
