Crystal structure of 10-benzyl-9-(3,4-di­meth­oxy­phen­yl)-3,3,6,6-tetra­methyl-3,4,6,7,9,10-hexa­hydro­acridine-1,8(2H,5H)-dione

In the acridinedione moiety of the title compound, C(32)H(37)NO(4), the central di­hydro­pyridine 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 cyclo­hexenone rings adopt envelope conformations, with the tetra­subsituted C atoms as the flap atoms. The 3,4-di­meth­oxy­­benzene and benzyl rings are almost normal to the di­hydro­pyridine mean plane, with dihedral angles of 89.47 (9) and 82.90 (11)°, respectively. In the crystal, mol­ecules 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).
