Crystal structure of 1-{3-acetyl-2-(4-chloro-phen-yl)-6-hy-droxy-4-[(2-hy-droxy-prop-yl)amino]-6-methyl-cyclo-hex-3-en-1-yl}ethanone.

In the title compound, C20H26ClNO4, the central cyclo-hexene ring adopts an approximate envelope conformation with the C atom binding with the hy-droxy group at the tip of the flap. There is an intramolecular N-H⋯O hydrogen bond generating an S(6) ring motif. In the crystal, classical O-H⋯O hydrogen bonds and weak C-H⋯O and C-H⋯Cl inter-actions link the mol-ecules, forming a three-dimensional supra-molecular architecture. The crystal structure was refined as a four-component twin.

Experimental. Analysis of 1837 reflections having I/σ(I) > 12 and chosen from the full data set with CELL_NOW (Sheldrick, 2008) showed the crystal to belong to the monoclinic system and to be twinned by a 180° rotation about the c* axis. The raw data were processed using the multi-component version of SAINT under control of the two-component orientation file generated by CELL_NOW.

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. H-atoms attached to carbon were placed in calculated positions (C—H = 0.95 - 0.98 Å) while those attached to oxygen were placed in locations derived from a difference map and their parameters adjusted to give O—H = 0.84 Å. All were included as riding contributions with isotropic displacement parameters 1.2 - 1.5 times those of the attached atoms. In the final stages of the refinement it became evident that not only was the crystal twinned by a 180° rotation about the c* axis but also each of these components was a racemic twin. Consequently, the model was finally refined as a 4-component twin.
