2,2'-[(E)-3-(4-Nitro-phen-yl)prop-2-ene-1,1-di-yl]bis-(3-hy-droxy-5,5-dimethyl-cyclo-hex-2-en-1-one)

Abstract

In the title compound, C(25)H(29)NO(6), each of the cyclo-hexenone rings adopts a half-chair conformation. The hy-droxy and carbonyl O atoms face each other and are oriented to allow for the formation of two intra-molecular O-H⋯O hydrogen bonds. In the crystal, weak C-H⋯O hydrogen bonds are formed between molecules, generating a two-dimensional supramolecular structure.
