title: N-(2-Fluoro-benzo-yl)-N',N''-bis-(4-methyl-phen-yl)phospho-ric triamide.
abstract: The P atom in the title compound, C(21)H(21)FN(3)O(2)P, is in a tetra-hedral coordination environment and the environment of each N atom is essentially planar (sums of angles = 359.7, 359.9 and 358.4°). The phosphoryl and carbonyl groups adopt anti orientations with respect to each other. In the crystal, adjacent mol-ecules are linked via N-H⋯O=P and two N-H⋯O=C hydrogen bonds into an extended chain parallel to the a axis.
