2-(Diphenylmethylidene)-2,3-dihydro-1H-inden-1-one

Abstract

In the title molecule, C22H16O, the indanone ring system is approximately planar with a dihedral angle between the fused rings of 5.13 (14)°. Two benzene rings are linked together at one side of a double bond, sitting on either side of the indanone ring system and making dihedral angles of 70.30 (12) and 44.74 (13)° with it. In the crystal, hydrogen bonding is not present, but weak C—H...π or π–π interactions occur and molecules form a sheet-like structure in the bc plane.
