title: 10-(4-Chloro-phen-yl)-9-(4-fluoro-phen-yl)-3,3,6,6-tetra-methyl-3,4,6,7,9,10-hexa-hydro-acridine-1,8(2H,5H)-dione.
abstract: The title compound, C(29)H(29)ClFNO(2), was synthesized by the reaction of 4-fluoro-benzaldehyde, 5,5-dimethyl-cyclo-hexane-1,3-dione and 3-(4-chloro-phenyl-amino)-5,5-dimethyl-cyclo-hex-2-enone in an ionic liquid (1-butyl-3-methyl-imidazolium bromide). X-ray analysis reveals that the 1,4-dihydro-pyridine ring adopts a boat conformation, while each of the attached partially saturated six-membered rings adopts a half-chair conformation. The structure is stabilized by weak C-H⋯O and C-H⋯F hydrogen bonds. The mol-ecule has approximate mirror symmetry; the largest deviation from this symmetry concerns the fluoro- and chloro-phenyl rings.
