title: Crystal structure of 10-benzyl-9-(3,4-di-meth-oxy-phen-yl)-3,3,6,6-tetra-methyl-3,4,6,7,9,10-hexa-hydro-acridine-1,8(2H,5H)-dione.
abstract: In the acridinedione moiety of the title compound, C32H37NO4, the central di-hydro-pyridine ring adopts a flattened-boat conformation, with the N atom and the methine C atom displaced from the mean plane of the other four atoms by 0.0513 (14) and 0.1828 (18) Å, respectively. The two cyclo-hexenone rings adopt envelope conformations, with the tetra-subsituted C atoms as the flap atoms. The 3,4-di-meth-oxy--benzene and benzyl rings are almost normal to the di-hydro-pyridine mean plane, with dihedral angles of 89.47 (9) and 82.90 (11)°, respectively. In the crystal, mol-ecules are linked via a pair of C-H⋯O hydrogen bonds, forming inversion dimers, which are, in turn, linked by C-H⋯O hydrogen bonds, forming slabs lying parallel to (001).
