【 摘 要 】

In the title compound, C21H22BrNO4, the tetrahydroacridine-1,8-dione unit has a bromohydroxyphenyl-substituent on the central carbon atom of the dihydropyridine ring and a 2-hydroxyethyl substituent on the nitrogen atom. An intramolecular O—H...O hydrogen bond forms between the hydroxyl substituent on the benzene ring and a carbonyl oxygen from the acridinedione, forming an S(8) ring. The hydroxyl group of the 2-hydroxyethyl residue is disordered over two sites with an occupancy ratio of 0.572 (6):0.428 (6). In the crystal structure O—H...O and C—H...O hydrogen bonds together with Br...O halogen bonds stack the molecules along the b-axis direction.
