The structures of as-synthesized SU-103 -SU-112 were solved and refined using three-dimensional electron diffraction (3D ED), also known as MicroED . Crystallographic details are presented in Supplementary Tables . The as-synthesized zirconium ellagate frameworks are formed from the coordination of Zr(IV) cations by the phenolic oxygens of the catechol groups of ellagic acid, which are either chelating or singly coordinating. While made from the same metal ions and organic ligands, the resulting frameworks exhibit a range of framework dimensionalities and topologies as imposed by the OSDAs. Structure models of each MOF and with the reagent used as OSDA are presented in Fig. , as well as Supplementary Fig. . Including also the previously reported SU-102, the zirconium-ellagate coordination of the synthesized phases using different OSDAs can be described using four topological nets: hcb, nbo, dia and pcu (Supplementary Fig. ). Notably, all of the nets are all so-called regular , where the vertices have a regular polygon or polyhedron as vertex figure and each net has a transitivity of 1111, i.e. only have 1 kind of vertex, 1 kind of edge, 1 kind of face, and 1 kind of tile. Four of the MOFs exhibit a porous layered structure with the hcb net (SU-104, SU-108, SU-110 and SU-111), specifically forming 2D porous hexagonal honeycomb networks. In these structures, four ellagate ligands coordinate to each Zr(IV), three of them chelating through both oxygen atoms of the catecholate group, while the fourth ellagate ligand coordinates only through one phenolic oxygen atom resulting in a coordination number of seven for the Zr(IV) cations (ZrO7). There are also π-π stacking interactions between ellagate anions which further stabilize the structures. In SU-104, SU-108 and SU-110, pairs of π-π stacked ellagate linkers bridge the same two Zr(IV) nodes, forming a double ellagate bridge (Supplementary Fig. ), yielding three-connected Zr(IV) nodes. In SU-111 on the other hand, one of the ellagate ligands is terminally coordinating while the remaining ellagate ligands singly bridge to three Zr(IV). This results in a notably different honeycomb network in which the terminally coordinating ellagate ligands are perpendicular to the layer, protruding out and π-π stacking with ellagates from neighbouring layers.
