N,N'-Dibenzyl-N,N'-dimethyl-N''-(4-nitro-benzo-yl)phospho-ric triamide
Abstract:
The P atom in the title compound, C(23)H(25)N(4)O(4)P, is in a slightly distorted tetra-hedral coordination environment and the N atoms show sp(2) character. The phosphoryl group and the NH unit are syn with respect to each other. In the crystal, pairs of inter-molecular N-H⋯O(P) hydrogen bonds form centrosymmetric dimers.
