N-(3-Fluorobenzoyl)-N′,N′′-bis(4-methylphenyl)phosphoric triamide

In the title compound, C21H21FN3O2P, the NH and P(=O) groups of the C(=O)NHP(=O) fragment are in a syn arrangement with respect to each other, as are the two amide H atoms of the two CH3–4-C6H4–NH moieties. In the crystal, molecules are linked through N—H...O(=P) and N—H...O(=C) hydrogen bonds, forming R22(8) and R22(12) rings, which are arranged in chains parallel to [010].
