Crystal structure of 9-(3-bromo-5-chloro-2-hydroxy­phen­yl)-10-(2-hy­droxy­eth­yl)-3,3,6,6-tetra­methyl-3,4,6,7,9,10-hexa­hydro­acridine-1,8(2H,5H)-dione

The title compound C(25)H(29)BrClNO(4), 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 the a-axis direction.
