(2E)-2-(Furan-2-ylmethylidene)-2,3-dihydro-1H-inden-1-one

In the title compound, C14H10O2, the five-membered ring of the inden-1-one residue is almost planar (r.m.s. deviation = 0.035 ). A twist about the single bond linking the two residues is evident [C—C—C—C torsion angle = 13.2 (5)°]. The three-dimensional architecture is stabilized by C—H...O (involving the trifurcated carbonyl O atom), C—H...π and π–π interactions [between the five- and six-membered rings of inden-1-one residues; ring centroid–centroid distance = 3.7983 (17) ]. The sample studied was a non-merohedral twin; the minor component refined to approximately 36%.
