ABSTRACT
Crystals of the title compound, C(18)H(26)O(2), were grown from ethyl acetate. Due to the racemic precursor, the title compound is also obtained as a racemate. Disorder was observed during structure refinement, originating from two possible half-chair conformations of the non-aromatic ring. The disorder was refined by introducing split positions in the cyclo-hexane ring regarding the two possible R and S-enantiomers at the chiral CH group [ratio 0.744â
(3)0.256â
(3)]. The crystal structure features pairs of inversion-related molecules connected by pairs of non-classical C-Hâ¯O hydrogen bonds.
