10-(4-Chlorophenyl)-9-(4-methoxyphenyl)3,3,6,6-tetramethyl-3,4,6,7-tetrahydroacridine-1,8(2H,5H,9H,10H)-dione

The title compound, C30H32ClNO3, was synthesized by the reaction of dimedone with 4-methoxy-benzaldehyde and 4-chloro-benzenamine in water. The dihydro-pyridine ring is in a boat conformation. Both cyclo-hexene rings adopt envelope conformations. The chloro-phenyl and methoxy-phenyl rings form dihedral angles of 81.31 (11) and 88.84 (12)°, respectively, with the planar part of the dihydro-pyridine ring. The crystal packing is stabilized by weak C - H⋯O hydrogen bonds. © International Union of Crystallography 2007.
