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

In the title compound, C(23)H(26)O(3), the three six-membered rings of the xanthene system are non-planar, having total puckering amplitudes, Q (T), of 0.443 (2), 0.202 (2) and 0.449 (2) Å. The central ring adopts a boat conformation and the outer rings adopt sofa conformations. The crystal structur...
