title: 9-(3-Bromo-5-chloro-2-hy-droxy-phen-yl)-10-(2-hy-droxy-eth-yl)-1,2,3,4,5,6,7,8,9,10-deca-hydro-acridine-1,8-dione.
abstract: In the title compound, C21H21BrClNO4, the dihydro-pyridine ring adopts a flattened boat conformation. The 3-bromo-5-chloro-2-hy-droxy-phenyl ring forms a dihedral angles of 84.44 (7)° with the dihydro-pyridine mean plane. 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 and C-H⋯O hydrogen bonds link the mol-ecules, forming a three-dimensional network.
