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

Abstract

In the molecule of the title compound, C24H28O4, the three six-membered rings of the xanthene system are not planar, having envelope, boat and envelope conformations. In the crystal structure, C—H...O hydrogen bonds link the molecules, generating centrosymmetric R22(12), R44(28) and R22(16) ring motifs and forming a three-dimensional network.
