N,N′-Dicyclo­hexyl-N′′,N′′-dimethyl­phospho­ric triamide

In the title compound, C(14)H(30)N(3)OP, 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 (CH(3))(2)NP(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 R (2) (2)(8) rings that are further linked into chains running parallel to the b axis.
