Abstract

In the title molecule, C15H16O3, the non‐H atoms of the benzoate group, the p‐carbonyl, the attached ring C and its substituent methyl group lie on a mirror plane bisecting the five‐membered ring, in which the C=C double bond is cis configured. Owing to symmetry considerations, the dihedral angle between the aromatic and the cyclopentyl rings is exactly 90°. There is an intermolecular C—H...O hydrogen bond, which links molecules into a one‐dimensional supramolecular chain along the c axis in a head‐to‐tail fashion. These supramolecular chains, in turn, interact with each other along the b axis through weak π–π contacts between neighboring aromatic rings [Cg...Cg and interplanar distances of 3.70 (1) and 3.33 (1) Å].
