- In the title compound, C25H29NO6, each of the cyclohexenone
rings adopts a half-chair conformation. Each of the pairs of
hydroxy and carbonyl O atoms are oriented to allow for the
formation of intramolecular O—HㆍㆍㆍO hydrogen bonds,
which are typical of xanthene derivatives. The nitro group is
rotationally disordered over two orientations in a
0.544 (6):0.456 (6) ratio. In the crystal, weak intermolecualr
C—HㆍㆍㆍO hydrogen bonds link molecules into layers parallel
to the ab plane.
