The title compound C25H29BrClNO4, comprises a 3,3,6,6-tetramethyltetrahydroacridine-1,8-dione ring system that carries a hydroxyethyl substituent on the acridine N atom and a 3-bromo-5-chloro-2-hydroxyphenyl ring on the central methine C atom of the dihydropyridine ring. The benzene ring is inclined to the acridine ring system at an angle of 89.84 (6)° and this conformation is stabilized by an intramolecular O—H...O hydrogen bond between the hydroxy substituent on the benzene ring and one of the carbonyl groups of the acridinedione unit. In the crystal, O—H...O, C—H...O and C—H...Br hydrogen bonds combine to stack molecules in interconnected columns propagating along thea-axis direction.
