9-(3-bromo-5-chloro-2-hydroxyphenyl)-10-(2-hydroxyethyl)-3,6-diphenyl-3,4, 9,10-tetrahydroacridine-1,8(2H,5H)-dione

Abstract

In the title compound, C33H27BrClNO4, the dihydropyridine ring adopts a flattened boat conformation. The molecular conformation is stabilized by an intramolecular 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 interactions link the molecules, forming a threedimensional 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.
