Abstract
The title compound, C11H12O, has been prepared as a side product in the attempted room-temperature synthesis of (E)-1-phenylpent-2-en-1-one. The molecular structure consists of an approximately planar indanone core (r.m.s. deviation = 0.042 A) with the ethyl group protruding from this plane. In the crystal, centrosymmetrically related molecules are linked into dimers by pairs of C—H⋯O hydrogen bonds, forming rings of R22(10) graph-set motif. The dimers are further connected by C—H⋯π interactions into chains running parallel to [-101].
