Figure 29. The cyanostar macrocycle and its complex with bisulfate anion dimers.

Figure 29

(D) Molecular structure of receptor 69.

(E) Top view of the crystal structure of the complex [(HSO4)2]2−⊂ 692.

(F) Front view of the crystal structure of the complex [(HSO4)2]2−⊂ 692.

All anions encapsulated within the cavity are shown in space-filling form. Color code: O = red, S = yellow. Different colors (pink and green) are used to highlight different independent ligands. The counter cations and solvent molecules outside the cavities are omitted for clarity.
