(2,4-Dihy-droxy-6-meth-oxy-phen-yl)(3,5-dihy-droxy-phen-yl)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 mol-ecule is twisted, the dihedral angle between the two benzene rings being 59.13 (7)°. The meth-oxy group is approximately coplanar with the attached benzene ring, with a C-O-C-C torsion angle of 1.91 (18)°. The water mol-ecule is disordered over two positions in a 0.555 (19):0.445 (19) ratio. An intra-molecular O-H⋯O hydrogen bond generates an S(6) ring motif. The crystal structure is stabilized by inter-molecular O-H⋯O hydrogen bonds. These inter-actions link the mol-ecules into sheets parallel to the ac plane. The sheets are stacked along the b axis by π-π inter-actions, with centroid-centroid distances of 3.6219 (7) Å. A weak O-H⋯π inter-action was also noted.
