N-(4-Fluoro­benzo­yl)-N′,N′′-diisopropyl­phospho­ric triamide

The asymmetric unit of the title phospho­ric triamide, C(13)H(21)FN(3)O(2)P, consists of two independent mol­ecules. In each mol­ecule, the P=O group and the N—H unit belonging to the C(O)NHP(O) fragment are in a syn conformation with respect to each other. An intra­molecular N—H⋯O hydrogen bond occurs in each mol­ecule. The P atom adopts a distorted tetra­hedral environment. The methyl groups of an isopropyl fragment are disordered over two sets of sites with refined occupancies of 0.458 (5) and 0.542 (5). In the crystal, mol­ecules are linked through N—H⋯O(=P) and N—H⋯O(=C) hydrogen bonds into chains along [001].
