title: Crystal structure of (E)-1-(4'-methyl-[1,1'-biphen-yl]-4-yl)-3-(3-nitro-phen-yl)prop-2-en-1-one.
abstract: In the title compound, C22H17NO3, the mol-ecule has an E conformation about the C=C bond, and the C-C=C-C torsion angle is -177.7 (3)°. The planes of the terminal benzene rings are twisted by 41.62 (16)°, while the biphenyl unit is non-planar, the dihedral angle between the planes of the rings being 38.02 (15)°. The dihedral angle between the nitro-phenyl ring and the inner benzene ring is 5.29 (16)°. In the crystal, mol-ecules are linked by two weak C-H⋯π inter-actions, forming rectangular tubes propagating along the b-axis direction.
