9-(2,4-Dichloro­phen­yl)-3,3,6,6-tetra­methyl-3,4,5,6-tetra­hydro-9H-xanthene-1,8(2H,7H)-dione

The title compound, C(23)H(24)Cl(2)O(3), 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 Å from the least-squares plane) while the two ou...

description The title compound, C(23)H(24)Cl(2)O(3), 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 Å 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)°] to the xanthene ring system.
