1-(3-p-Tolyl-isoxazol-5-yl)cyclo-hexa-nol.

Acta Crystallogr Sect E Struct Rep Online 2009 Nov 4;65(Pt 12):o2971. Epub 2009 Nov 4.

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.
