title: 6-[3-(2,4-Dimethyl-anilino)-2-hydroxy-prop-oxy]-1,8-dihydr-oxy-3-methyl-9,10-dihydro-anthracene-9,10-dione.
abstract: In the title compound, C(26)H(25)NO(6), the anthraquinone ring system forms a dihedral angle of 15.5 (1)° with the benzene ring of the dimethyl-aniline group. Intra-molecular O-H⋯O hydrogen bonding is observed between the carbonyl and two hydroxyl groups. The mol-ecules are linked into a ribbon-like structure along the [100] direction by O-H⋯N and C-H⋯O hydrogen bonds. The crystal used was twinned via a 180° rotation about [100]. The ratio of the two twin components is 0.947 (1):0.053 (1).
