title: N,N-Dimethyl-N',N''-diphenyl-phospho-ric triamide.
abstract: In the title compound, C(14)H(18)N(3)OP, a crystallographic mirror plane bis-ects the mol-ecule (the C,N,C atoms of the dimethyl-amido moiety and the P=O unit lie on the mirror plane). The P atom has a distorted tetra-hedral geometry; the bond angles at P are in the range 98.98 (11)-115.28 (7)°. In the crystal, the O atom of the P=O group acts as a double hydrogen-bond acceptor for two symmetry-equivalent N-H⋯O hydrogen bonds, building [001] chains containing R(2) (1)(6) loops.
