In the C(O)NHP(O) fragment of the title compound, C35H32F2N3O2P, the P-N bond is longer and the O-P-N angle is contracted compared with the other two P-N bonds and O-P-N angles. The P atom adopts a distorted tetrahedral environment and the phosphoryl and carbonyl groups are anti with respect to each other. The two tertiary N atoms of the dibenzylamido groups show sp2 character with a slight deviation from planarity. In the crystal, pairs of N-HO(P) hydrogen bonds form inversion dimers.
