(2E)-2-(Furan-2-yl-methyl-idene)-2,3-dihydro-1H-inden-1-one

Abstract

In the title compound, C14H10O2, the five-membered ring of the inden-1-one residue is almost planar (r.m.s. deviation = 0.035 Å). 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 inter-actions [between the five-and six-membered rings of inden-1-one residues; ring centroid-centroid distance = 3.7983 (17) Å]. The sample studied was a non-merohedral twin; the minor component refined to approximately 36%.
