title: (E)-1-([1,1'-Biphen-yl]-4-yl)-3-(2-methyl-phen-yl)prop-2-en-1-one.
abstract: In the title mol-ecule, C22H18O, the o-tolyl ring is connected through a conjugated double bond. The mol-ecule adopts an E conformation and the C-C=C-C torsion angle is 178.77 (13)°. The overall conformation may be described by the values of dihedral angles between the different planes. The terminal rings are twisted by an angle of 54.75 (8)°, while the biphenyl part is not planar, the dihedral angle between the planes of the rings being 40.65 (8)°. The dihedral angle between the benzene rings is 14.10 (7)°. There are three weak C-H⋯π inter-actions found in the crystal structure. No classic hydrogen bonds are observed.
