N-(2-Chloro-2,2-difluoro-acet-yl)-N',N''-diisopropyl-phospho-ric triamide.

ABSTRACT: In the title compound, C(8)H(17)ClF(2)N(3)O(2)P, the phosphoryl group and the NH unit of the C(O)NHP(O) moiety adopt a syn conformation with respect to each other. The P atom is in a tetra-hedral coordination environment and the environment of the N atom of the C(O)NHP(O) moiety is essentially planar. In the crystal, adjacent mol-ecules are linked via N-H?O =P and N-H?O =C hydrogen bonds, building R(2) (2)(8) and R(2) (2)(12) rings in a linear arrangement parallel to [110].
