Figure 17. Arene-based hexapodal amide receptors and their anionic complexes.

Figure 17

(A) Molecular structures of receptors 41–43.

(B) Single crystal X-ray structure of the complex [(NO3)4(H2O)2]4− ⊂ 41.

(C) Single crystal X-ray structure of the complex [F4(H2O)10]4− ⊂ 422.

(D) Single crystal X-ray structure of the complex [F4(H2O)6]4− ⊂ 432.

All anions encapsulated within the cavity are shown in space-filling form. Color code: C = gray, N = blue, O = red, and F = chartreuse yellow. The counter cations and solvent molecules outside the cavities are omitted for clarity.
