The remaining six synthesized MOFs exhibit 3D framework structures with three distinct topologies (nbo, dia, pcu). Notably, SU-103 is the only structure in which pairs of Zr(IV) cations share two oxygen atoms, resulting in a dimeric Zr2O12 inorganic building unit (IBU) that is connected to six other nodes in a cubic arrangement, forming a primitive cubic net, pcu (Supplementary Fig. ). The previously described SU-102 material exhibits a nbo topology, in which Zr(IV) cations are eight-coordinated and all ligands participate in π-π stacking interactions, which significantly contribute to the stability and structural integrity of the network. The most common topology among the synthesized MOFs is the dia net, as observed for SU-105, SU-106, SU-107, SU-109 and SU-112. In these structures, each Zr(IV) node is coordinated by four ellagate ligands in a tetrahedral arrangement to form 3D diamond nets. Among the five frameworks, the Zr(IV) cations in SU-107 and SU-109 are seven-coordinated, while eight-coordinated Zr(IV) nodes are present in SU-105, SU-106 and SU-112 (Supplementary Fig. ). SU-107 possesses the largest pores of the 3D frameworks, and its crystals are well ordered as observed by optimum bright field scanning transmission electron microscopy (OBF-STEM) imaging, as shown in Fig. . Two of the six walls around each hexagonal pore have higher contrast since those walls have twice the density of ellagate linkers compared to the other four walls. SU-106 and SU-112 exhibit interpenetrated structures both comprising of the same individual frameworks. However, in SU-106, the two interpenetrated frameworks are related by translational symmetry, whereas in SU-112 the same two interpenetrated frameworks are not only translated with respect to one another but also rotated 90°. Therefore, in SU-106 the planar ellagate linkers are all aligned parallel to the channel direction, which contrasts with SU-112 where one of the frameworks has ellagates aligned perpendicular to the channels. Thus, these two phases are not interchangeable.
