Abstract

In the title chalcone derivative, C19H18O3, the cyclo-hexa-none ring adopts a distorted half-chair conformation and the dihedral angle between the aromatic rings is 52.20 (15)°. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules into C(12) [001] chains.

Keywords: chalcone derivative; crystal structure.
