Figure 8. Tripodal receptors and their anionic complexes.

Figure 8

(A) Molecular structures of receptors 16 and 17.

(B) Single crystal structure of the complex [(H2PO4)4]4−⊂ 164.

(C) Single crystal structure of the complex [F4(H2O)5]4−⊂ [H417]4+2.

(D) Single crystal structure of the complex [Cl6]6−⊂ [H417]4+2.

All anions encapsulated in the cavities are shown in space-filling form. Color code: C = gray, N = blue, O = red, F = chartreuse yellow, P = yellow, and Cl = green. Most counter ions and solvent molecules outside the cavities are omitted for clarity.
