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.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
