1,6-Dihydr­oxy-3-hydroxy­methyl-8-methoxy­anthracene-9,10-dione monohydrate

By Wen-Liang Wang, Wei Sun, Qian-Qun Gu and Wei-Ming Zhu


The title compound, C16H12O6·H2O, isolated from the halotolerant fungus Aspergillus variecolor B-17, is also known as questinol monohydrate. In the crystal structure, O—H⋯O hydrogen bonds link the mol­ecules, forming a three-dimensional network. π–π stacking inter­actions consolidate the supra­molecular structure [the shortest inter­planar distances are 3.456 (3), 3.366 (4) and 3.382 (4) Å]
