(R,E)-3-(4-Chloro-phen-yl)-1-phenyl-allyl 4-nitro-benzoate.
The title compound, C(22)H(16)ClNO(4), adopts a conformation in which the phenyl ring plane forms similar dihedral angles with the nitro-benzoate C(6) ring [76.97 (8)°] and the chloro-phenyl group [76.95 (8)°]; the dihedral angle between the chloro-phenyl and nitro-benzoate rings is 66.43 (8)°. In the crystal, π-π stacking is observed between the latter two planes, with a dihedral angle of 1.79 (8)° and a centroid-centroid distance of 3.735 (1) Å. In addition, mol-ecules are linked along [100] by weak C-H⋯O contacts.
