In the quinolone ring system of the title compound, C₁₅H₁₀Cl₃NO, the pyridone moiety assumes a slightly twisted boat conformation. The plane of the benzene ring is twisted at an angle of 11.9(1)° with respect to the pyridone ring, indicating the slight non-planarity of the system. The molecules are stabilized by N-H...-O-type hydrogen bonds in addition to van der Waals interactions.
