title: 3-Hy-droxy-2-[(2-hy-droxy-4,4-dimethyl-6-oxocyclo-hex-1-en-1-yl)(3-nitro-phen-yl)meth-yl]-5,5-dimethyl-cyclo-hex-2-en-1-one.
abstract: Each of the cyclohexenone rings in the title compound, C(23)H(27)NO(6), adopts a half-chair (envelope) conformation with the C atom carrying the methyl groups lying out of the plane defined by the five remaining C atoms; the O atoms lie to the same side of the mol-ecule as the respective >C(CH(3))(2) atoms. The hy-droxy and carbonyl O atoms face each other and are orientated to allow for the formation of two intra-molecular O-H⋯O hydrogen bonds. In the crystal, the presence of C-H⋯O contacts leads to the formation of supra-molecular chains along the b axis. These aggregate into layers that stack along c.
