N,N #8242;-Dicyclohexyl-N #8242; #8242;,N #8242; #8242;-dimethylphosphoric triamide

In the title compound, C14H30N3OP, both cyclohexyl groups adopt chair conformations with the NH unit in an equatorial position. The P atom adopts a slightly distorted tetrahedral environment. In the (CH3)2NP(O) unit, the O—P—N—C torsion angles, showing the orientations of the methyl groups with respect to the phosphoryl group, are −166.6 (3) and 34.6 (4)°. The O atom of the P=O group acts as a double hydrogen-bond acceptor and is involved in two different intermolecular N—H...OP hydrogen bonds, building R22(8) rings that are further linked into chains running parallel to the b axis.
