N,N′-Dibenzyl-N′′-(2,4-difluoro­benzo­yl)-N,N′-dimethyl­phospho­ric triamide

In the title mol­ecule, C(23)H(24)F(2)N(3)O(2)P, the P atom is in a distorted tetra­hedral P(=O)(N)(N)(2) environment, with the bond angles around the P atom in the range 106.78 (11)–114.10 (13)°. The phosphoryl and carbonyl groups, which are separated by an N atom, adopt an anti orientation relative to each other. In the C(=O)NHP(=O) fragment, the P—N bond is longer [1.683 (2) Å] and the O—P—N angle is smaller [106.78 (11)°] than the other P—N bonds [1.613 (2) and 1.632 (2) Å] and O—P—N bond angles [114.10 (13) and 110.83 (12)°], respectively. The N atoms have sp (2) character. In the crystal, pairs of P=O⋯H—N hydrogen bonds form inversion dimers with R (2) (2)(8) ring motifs.
