Abstract top

In the title compound, C19H30N3O2P, the central P atom has a distorted tetrahedral configuration. The N atoms in both cyclohexylamide moieties exhibit a slight deviation [0.32 (7) and 0.44 (6) Å] from planarity, while the benzoylamide N atom is planar [0.11 (3) Å]. In the crystal, molecules are linked via N-H...O(P) and N-H...O(C) hydrogen bonds, forming R22(10) rings within linear arrangements parallel to the b axis.

Comment top

The synthesis of the title compound, C6H5C(O)NHP(O)[NHC6H11]2, was previously published by Gholivand et al. (2006). Here, we report its crystal structure (Fig. 1).

The PO, CO and P—N bond lengths match those found for other compounds with the [(N)(N)P(O)NHC(O)] skeleton (Sabbaghi et al., 2010). The nitrogen atoms show sp2 character and the environment of N atom in C(O)NHP(O) moiety is practically planar. The tetrahedral configuration of phosphorus atom is significantly distorted (Fig. 1) as it has been noted for other phosphoric triamides and their chalco-derivatives (Rudd et al., 1996): the bond angles at the P atom vary in the range from 102.7 (2)° to 117.2 (2)°, while the P–N bond distances range form 1.615 (4) to 1.730 (4) Å. Cyclohexyl groups are in a chair conformation with the adjacent NH groups oriented equatorially.

The NH unit of the C(O)NHP(O) moiety adopts a syn orientation with respect to the phosphoryl group; moreover, the NH units of two C6H11NH moieties are in a syn orientation with respect to each other.

In the crystal structure, the molecules are linked via N—H···OP and N—H···OC hydrogen bonds, in which carbonyl oxygen interacts with benzamide N—H and P(O) group binds to a cyclohexylamido moiety. This way, R22(10) rings are built (Etter et al., 1990; Bernstein et al., 1995), that are further connected in linear arrangements along y axis (Table 1, Fig. 2).

Experimental top

C6H5C(O)NHP(O)[NHC6H11]2 was prepared according to the procedure reported by Gholivand et al. (2006). Single crystals of title compound were obtained from CH3OH after slow evaporation at room temperature.

Refinement top

At the end of the refinement the highest peak in the electron density was 0.460 e Å -3, while the deepest hole was -0.180 e Å -3.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
