N,N'-Bis(2-methyl-phen-yl)-N''-(2,2,2-trichloro-acet-yl)phospho-ric triamide

In the title compound, C(16)H(17)Cl(3)N(3)O(2)P, the P-N bonds in the P(O)[NH(2-CH(3))C(6)H(4)](2) unit [1.623 (4) and 1.637 (3) Å] are shorter than the P-N bond in the C(O)NHP(O) fragment [1.704 (3) Å]. The phosphoryl and carbonyl groups are anti with respect to each other and the P atom has a distorted tetra-hedral configuration. In the crystal, adjacent mol-ecules are linked via N-H⋯O(P) and N-H⋯O(C) hydrogen bonds into an extended chain parallel to [101].
