Abstract

In the title compound, C18H14O, with systematic name 1-(anthracen-9-yl)-2-methylprop-2-en-1-one, the ketonic C atom lies 0.2030 (16) angstrom out of the anthrylring-system plane. The dihedral angle between the planes of the anthryl and methacryloyl moieties is 88.30 (3)degrees and the stereochemistry about the Csp(2) - Csp(2) bond in the side chain is transoid. In the crystal, the end rings of the anthryl units in adjacent molecules associate in parallel-planar orientations [shortest centroid-centroid distance = 3.6320 (7) angstrom]. A weak hydrogen bond is observed between an aromatic H atom and the O atom of a molecule displaced by translation in the a-axis direction, forming sheets of parallel-planar anthryl groups packing in this direction.
