In the pyridone ring of the title compound, C 19 H 20 ClNO 2 , single and double bonds alternate, though allowing some degree of conjugation. One C atom in the cycloheptene ring is disordered over two positions, which form boat and chair conformations of cycloheptene, respectively.

In the pyridone ring of the title compound, C 20 H 22 ClNO 2 , single and double bonds alternate, though allowing some degree of delocalization. Two C atoms in the cyclooctene ring are disordered, indicating some ¯exibility of the large ring.
