(2,4-Dihy­droxy-6-meth­oxy­phen­yl)(3,5-dihy­droxy­phen­yl)methanone monohydrate

The title benzophenone compound, C(14)H(12)O(6)·H(2)O, was isolated from the bark of Garcinia hombroniana Pierre (Guttiferae). The mol­ecule is twisted, the dihedral angle between the two benzene rings being 59.13 (7)°. The meth­oxy group is approximately coplanar with the attached benzene ring, with a C—O—C—C torsion angle of 1.91 (18)°. The water mol­ecule is disordered over two positions in a 0.555 (19):0.445 (19) ratio. An intra­molecular O—H⋯O hydrogen bond generates an S(6) ring motif. The crystal structure is stabilized by inter­molecular O—H⋯O hydrogen bonds. These inter­actions link the mol­ecules into sheets parallel to the ac plane. The sheets are stacked along the b axis by π–π inter­actions, with centroid–centroid distances of 3.6219 (7) Å. A weak O—H⋯π inter­action was also noted.
