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.
在标题化合物C₃₃H₂₇BrClNO₄中，二氢吡啶环呈扁平船式构象。分子构象通过分子内O—H⋯O氢键得以稳定，形成S(8)环模式。在晶体中，O—H⋯O、C—H⋯O和C—H⋯Cl氢键以及C—H⋯π相互作用将分子连接起来，形成三维网络。在吖啶二酮环系中，2-和3-位的两个环碳原子、6-位的碳原子以及连接在6-位碳原子上的苯环原子在两组位置上无序排列，占有率分别为0.783 (5):0.217 (5)和0.526 (18):0.474 (18)。
