Abstract:The structure of the title natural product, 1′,5-dihydroxy-3′,7-dimethyl-2,2′-binaphthalene-1,4,5′,8′-tetrone, C22H14O6, confirms the atomic connectivity postulated on the basis of spectroscopic data. The geometric parameters are normal and the angle between the planes of the two ring systems is 59.74 (2)°. The crystal packing is influenced by O—H…O hydrogen bonds, and possible short C—H…O and – stacking interactions.
