(E)-2,2'-[3-(2-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. Each of the pairs of hy-droxy and carbonyl O atoms are oriented to allow for the formation of intra-molecular O-H⋯O 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 inter-molecualr C-H⋯O hydrogen bonds link mol-ecules into layers parallel to the ab plane.
