Abstract
In the title compound, C9H8O2, a benzo-annulated heterocyclic ketone, the non-aromatic six-membered ring adopts an E2 conformation. In the crystal, C—H⋯O contacts connect the molecules into double sheets perpendicular to the crystallographic a axis. The centroid–centroid distance for two π-systems is 3.7699 (6) Å.
