3-[(E)-2-(4-Chloro­phen­yl)ethen­yl]-5,5-di­methyl­cyclo­hex-2-en-1-one

In the title compound, C₁₆H₁₇ClO, the cyclo­hexene 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 mol­ecules into centrosymmetric R₂²(20) dimers. The dimers are linked into an infinite chains along the b-axis direction by further C—H...O hydrogen bonds.
