چکیده
The title compound C25H29BrClNO4, comprises a 3,3,6,6-tetra-methyl-tetra-hydro-acridine-1,8-dione ring system that carries a hy-droxy-ethyl substituent on the acridine N atom and a 3-bromo-5-chloro-2-hy-droxy-phenyl ring on the central methine C atom of the di-hydro-pyridine 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 intra-molecular O-H⋯O hydrogen bond between the hy-droxy 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 mol-ecules in inter-connected columns propagating along the a-axis direction.
