In the crystal structure of the title compound, C15H11Cl2NO, the Cl - C - Cl plane is nearly perpendicular to the four-membered β-lactam ring [89.0(2)°] and the C - C bond distances in this group are 1.571 (6) and 1.543 (7) Å. The most out-of-plane atom from the best plane of the lactam ring is the carbonyl C atom [-0.029(5) Å]. The dihedral angle between the best planes of the phenyl rings is 77.4(2)°.
