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

ABSTRACT: In the title compound, C(23)H(24)N(2)O(7), the central 4H-pyran ring adopts a flattened boat conformation, whereas both cyclo-hexenone rings adopt envelope conformations, the C atom bearing the dimethyl substituent being the flap atom in each case. The mean and maximum deviation of the pyran ring are 0.0379?(4) and 0.0605?(3)?Å. The mean plane of the pyran ring and the dinitro-benzene ring make a dihedral angle of 85.88?(2)°.

Project description: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.
