Abstract

The title compound, C(16)H(19)NO(2), contains two mol-ecules in the asymmetric unit. Each mol-ecule is composed of three inter-connected rings, two essentially planar rings, viz. the isoxazole and the methyl-benzyl aromatic ring [maximum deviations of 0.0027 (13) and 0.0031 (19) Å from the isoxazole and methylbenzyl ring planes, respectively, in the first molecule, 0.0018 (12) and 0.019 (2) Å in the second molecule], and one cyclo-hexa-nol ring having a chair conformation. Although the two mol-ecules have similar bond distances and angles, they differ in the orientation of the cyclo-hexa-nol ring with respect to the tolyl-isoxazole unit. In the first mol-ecule, the dihedral angle between the isoxazole and methyl-benzyl rings is 22.03 (8)° and between the isoxazole and cyclo-hexa-nol rings is 30.15 (8)°. The corresponding values in the second mol-ecule are 6.13 (10) and 88.44 (8)°, respectively. In the crystal, the molecules are linked by O-H⋯O and O-H⋯N hydrogen bonds, building up a zigzag chain parallel to the a axis.

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