摘要
The title compound, C23H24Cl2O3, was synthesized by reaction of 2,4-dichlorobenzaldehyde and 5,5-dimethylcyclohexane-1,3- dione in ethylene glycol. The central ring of the xanthene moiety is almost planar (with an r.m.s. deviation of 0.0268 angstrom from the least-squares plane) while the two outer rings, in a cis arrangement, display envelope conformations. The ring of the 2,4-dichlorophenyl substituent is nearly perpendicular [85.89 (4)degrees] to the xanthene ring system.
