9-(2,4-Dichloro-phen-yl)-3,3,6,6-tetra-methyl-3,4,5,6-tetra-hydro-9H-xanthene-1,8(2H,7H)-dione.

ABSTRACT: The title compound, C(23)H(24)Cl(2)O(3), was synthesized by reaction of 2,4-dichloro-benzaldehyde and 5,5-dimethyl-cyclo-hexane-1,3-dione in ethyl-ene 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-dichloro-phenyl substituent is nearly perpendicular [85.89?(4)°] to the xanthene ring system.
