title: (E)-4-(2-Chloro-1-hy-droxy-2,6,6-tri-methyl-cyclo-hex-yl)but-3-en-2-one.
abstract: In the title mol-ecule, C13H21ClO2, there is an intra-molecular C-H⋯Cl hydrogen bond. The conformation about the C=C bond is E and the six-membered ring has a chair conformation. In the crystal, mol-ecules are linked by pairs of O-H⋯O hydrogen bonds, forming inversion dimers, which are consolidated by C-H⋯O hydrogen bonds. The dimers are linked via C-H.·O hydrogen bonds, forming chains along [100].
