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

[摘要] In the title compound, C21H15NO3, the mol­ecule has an E conformation about the C=C bond, and the C—C=C—C torsion angle is −178.24 (18)°. In the mol­ecule, the planes of the terminal rings are twisted by an angle of 42.19 (10)°, while the biphenyl part is not planar, with a dihedral angle between the rings of 39.2 (1)°. The dihedral angle between the nitro­phenyl ring and the inner benzene ring is 5.56 (9)°. The 3-nitro group is approximately coplanar with the benzene ring to which it is attached [O—N—C—C = 0.1 (3)°]. In the crystal, mol­ecules are linked via C—H⋯π inter­actions, involving the terminal benzene rings, forming corrugated layers parallel to (100).
