The title compound, C24H14O9·H2O, displays a cup-shaped form. The water molecule is disordered over two set of sites with an occupancy ratio of 0.78:0.22. The molecule of the compound has four stereocenters and corresponds to the SSRR/RRSS diastereoisomer. In the molecule, the maximum dihedral angle between the planar benzene rings is 80.40 (4)°. The H atoms of the hydroxy groups are engaged in hydrogen bonding, forming infinite chains parallel to the a axis. These chains are interlinked through water molecules, 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 interactions result in the formation of a three-dimensional network.
