Extended Data Fig. 2: Structure analysis of triangular modules in RP-H101.
From: Balancing volumetric and gravimetric capacity for hydrogen in supramolecular crystals
a, The crystal superstructure of RP-H101 shows the interpenetration of 6.4-nm hexagonal motifs denoted in different colours. After interpenetration, every 6.4-nm hexagonal motif forms 12 triangular modules. b, c, The top-view and side-view of how the triangular module is assembled. Each triangular module shows a three-layer structure assembled with five IATH-2 molecules. d, Each triangular module has a triangular prism-shaped pore, with a pore diameter of 1.5 nm. e, From the side-view of the triangular module, there are six [N−H···O] and six [O−H···N] hydrogen bonds between these 5 IATH-2 molecules, directing the formation of the highly catenated structure.
