title: 2,6-Dimethyl-4-m-tolyl-cyclo-hex-3-enecarboxylic acid.
abstract: The title compound, C(16)H(20)O(2), was synthesized to study the hydrogen-bonding inter-action of the two enanti-omers in the solid state. The racemate is made up of carboxylic acid RS dimers. Inter-molecular O-H⋯O hydrogen bonds produce centrosymmetric R(2) (2)(8) rings which dimerize the two chiral enanti-omers through their carboxyl groups. The chirality of this compound is generated by the presence of the double bond in the cyclo-hexene ring and a chiral axis due to the meta-methyl substituent on the aromatic ring.
