title: (E)-2,2'-[3-(2-Nitro-phen-yl)prop-2-ene-1,1-di-yl]bis-(3-hy-droxy-cyclo-hex-2-en-1-one).
abstract: In the title compound, C(21)H(21)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.
