The molecular packing in (I): (a) dimeric aggregate comprising centrosymmetrically related 1,8-dihydroxyanthraquinone molecules connected by hydroxy-O—H⋯O(carbonyl) hydrogen bonds and (b) a view of the unit-cell contents in projection down the b axis. The O—H⋯O and phenyl-C—H⋯O(carbonyl) interactions are shown as orange and blue dashed lines, respectively. |
