Crystal structure of (E)-1-(4′-methyl-[1,1′-biphenyl]-4-yl)-3-(3-nitrophenyl)prop-2-en-1-one

In the title compound, C22H17NO3, the molecule 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 nitrophenyl ring and the inner benzene ring is 5.29 (16)°. In the crystal, molecules are linked by two weak C—H...π interactions, forming rectangular tubes propagating along the b-axis direction.
