چکیده
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.

The title compound, C(18)H(16)O(7)·H(2)O, is a flavonoid isolated from Dodonaea viscosa-. The benzopyran ring system of the flavonoid is essentially planar [maximum deviation = 0.025 (2) Å] and inclined at 5.83 (2)° to the attached benzene ring. The water of hydration is involved in extensive hydrogen bonding, assembling the mol-ecules into a supra-molecular network via classical inter-molecula...

In the title compound, C(15)H(12)O(4)·H(2)O, the two benzene rings are not coplanar, making a dihedral angle of 7.24 (16)°. An intra-molecular hy-droxy-carbonyl O-H⋯O hydrogen bond occurs. In the crystal, four inter-molecular O-H⋯O hydrogen bonds involving the hy-droxy residues, the carbonyl group and the water mol-ecule lead to the formation of a three-dimensional network. The supra-molecular ...
