title: N,N'-Dimethyl-N''-(trichloroacet-yl)phospho-ramide.
abstract: In the title compound, C4H9Cl3N3O2P or CCl3C(O)NHP(O)(NHCH3)2, the P atom has a strongly distorted tetra-hedral geometry due to the formation of intermolecular strong hydrogen bonds involving the N atoms. In the crystal, N-H⋯O=P and N-H⋯O=C hydrogen bonds connect the mol-ecules into a two-dimensional array parallel to (100). An intra-molecular P⋯O contact [P⋯O = 2.975 (3) Å] is observed. The CCl3 group is rotationally disordered, with occupancies of 0.60 (3) and 0.40 (3).
