Fig. 6: Supramolecular tessellations of P4 with TPN.
From: Supramolecular tessellations by the exo-wall interactions of pagoda[4]arene
Crystal structure of P4-TPNa showing a the asymmetric unit; b the interactions between P4 and TPN. Crystal structure of P4-TPNb showing c the asymmetric unit; d interactions in the basic tiling unit; e schematic representation of the basic tiling unit; f two-dimensional tiling of the uniform superstructure formed by P4 and TPN in a plane; g regular parallelogram grids formed by TPN molecules. Different colors represent the symmetry equivalence. Green, black, and red dotted lines represent the noncovalent interactions. Crystallographically independent P4 and TPN molecules were marked as P4-1, P4-2, TPN-1, TPN-2, TPN-3, and TPN-4, respectively.
