title: (±)-4,12,15,18,26-Penta-hydroxy-13,17-dioxahepta-cyclo-[14.10.0.0.0.0.0.0]hexa-cosa-1,3(14),6(11),7,9,15,19,21,23-nona-ene-5,25-dione monohydrate.
abstract: The title compound, C(24)H(14)O(9)·H(2)O, displays a cup-shaped form. The water mol-ecule is disordered over two set of sites with an occupancy ratio of 0.78:0.22. The mol-ecule of the compound has four stereocenters and corresponds to the SSRR/RRSS diastereoisomer. In the mol-ecule, the maximum dihedral angle between the planar benzene rings is 80.40 (4)°. The H atoms of the hy-droxy groups are engaged in hydrogen bonding, forming infinite chains parallel to the a axis. These chains are inter-linked through water mol-ecules, resulting in the formation of a two-dimensional network parallel to the (001) plane. Futhermore C-H⋯O, C-H⋯π and slipped π-π inter-actions result in the formation of a three-dimensional network.
