N,N,N',N'-Tetra-ethyl-N''-(2-fluoro-benzo-yl)phospho-ric triamide.

ABSTRACT: 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 tetra-hedral 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 fluoro-benzene ring about its connecting C-C bond. In the crystal, pairs of inter-molecular N-H?O(=P) hydrogen bonds form centrosymmetric dimers.
