N,N′-Dicyclohexyl-N,N′-dimethyl-N′′-(4-nitro- benzoyl)phosphoric triamide

Abstract

The P atom in the title compound, C21H33N 4O4P, is in a slightly distorted tetra-hedral coordination environment and the phosphoryl and carbonyl groups are anti to each other. The environment of each N atom is essentially planar (average angles of 119.9 and 118.4°). In the crystal structure, the H atom of the C(=O)NHP(=O) group is involved in an inter-molecular-P=O⋯H-N-hydrogen bond, forming centrosymmetric dimers.
