(a) Asymmetric unit with the selected atom-labeling scheme of the dihydrate. The ellipsoids are shown at 50% probability. (b) Crystal structure of a dinuclear unit of the dihydrate. (c) View of the packing structure of the dihydrate with hydrogen bonds between the coordinated water and PDA-OXA (dashed lines). (d) 3D supramolecular framework with open 1D channels and and (e) packing diagrams along the b axis, respectively. (f) The consistency of the `voids' and the reverse arrangement of PDA molecules shown in different colors.
