title: 3-[(E)-2-(4-Chloro-phen-yl)ethen-yl]-5,5-di-methyl-cyclo-hex-2-en-1-one.
abstract: In the title compound, C16H17ClO, the cyclo-hexene ring adopts a half-chair conformation and the best plane through the six ring atoms makes a dihedral angle of 6.69 (7)° with the chlorophenyl ring. In the crystal, pairs of C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric R 2 (2)(20) dimers. The dimers are linked into an infinite chains along the b-axis direction by further C-H⋯O hydrogen bonds.
