title: 9-(3-Bromo-5-chloro-2-hy-droxy-phen-yl)-10-(2-hy-droxy-eth-yl)-3,6-diphenyl-3,4,9,10-tetra-hydro-acridine-1,8(2H,5H)-dione.
abstract: In the title compound, C33H27BrClNO4, the di-hydro-pyridine ring adopts a flattened boat conformation. The mol-ecular conformation is stabilized by an intra-molecular O-H⋯O hydrogen bond, with an S(8) ring motif. In the crystal, O-H⋯O, C-H⋯O and C-H⋯Cl hydrogen bonds, and C-H⋯π inter-actions link the mol-ecules, forming a three-dimensional network. In the acridinedione ring system, the two ring C atoms at the 2- and 3-positions, and the C atom at the 6-position and the atoms of the phenyl ring attached to the C atom at the 6-position are disordered over two sets of sites with occupancy ratios of 0.783 (5):0.217 (5) and 0.526 (18):0.474 (18), respectively.
