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

In the title compound, C(23)H(25)NO(5), the pyran ring adopts a flattened boat conformation, while the two cyclo­hexenone rings are in envelope conformations. The 3-nitro­phenyl ring is almost perpendicular to the pyran ring, making a dihedral angle of 87.1 (3)°.
