The structure of 9-(3-bromo-6-chloro-2-hy­droxy­phen­yl)-10-(2-hy­droxy­ethyl)-3,6-diphenyl-3,4,5,6,7,9-hexa­hydro-2H-acridine-1,8-dione

In the structure of the title compound C33H29BrClNO4, (I), the hexa­hydro-2H-acridine ring system has a hy­droxy­ethyl substituent on the N atom and a 3-bromo-6-chloro-2-hy­droxy­phenyl substituent on the central C atom at the 9-position. An unusual feature of the mol­ecule is that the substituents at the 3- and 5-positions of the outer cyclo­hexenone rings are phenyl rings rather than the more common dimethyl substituents. C atoms on both of the cyclo­hexenone rings are disordered over two sites. In the crystal structure, O—H⋯O, C—H⋯O and C—H⋯π(ring) hydrogen bonds combine with an Br—O and unusual C—Br⋯π(ring) halogen bonds to generate a three dimensional network with mol­ecules stacked along the a-axis direction.
