title: N,N'-Dicyclo-hexyl-N'',N''-dimethyl-phospho-ric triamide.
abstract: In the title compound, C(14)H(30)N(3)OP, both cyclo-hexyl groups adopt chair conformations with the NH unit in an equatorial position. The P atom adopts a slightly distorted tetra-hedral 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 inter-molecular N-H⋯OP hydrogen bonds, building R(2) (2)(8) rings that are further linked into chains running parallel to the b axis.
