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