N,N′-Dibenzyl-N,N′-dimethyl-N″-(2-phenylacetyl)phosphoric triamide

Abstract

The P atom in the title molecule, C24H28N 3O2P, is in a distorted tetra-hedral P(=O)(N)(N) 2 environment. The phosphoryl group and the NH unit adopt a syn orientation with respect to each other and the N atoms have sp 2 character. The P-N bonds in the P(O)[N(CH3)(CH2C 6H5)]2 unit are shorter than the P-N bond in the C(=O)NHP(=O) fragment. An intramolecular C - H⋯O hydrogen bond occurs. In the crystal, pairs of P=O⋯H-N hydrogen bonds form centrosymmetric dimers. C-H⋯O contacts are also observed. Four C atoms of two benzene rings are disordered over two alternative sites with an occupancy ratio of 0.523 (12):0.427 (12).
