Figure 42. Tricyclic receptor 86 and solid state structures of selected anion complexes.

Figure 42

(A) Molecular structure of receptor 86.

(B) The crystal structure of the complex [(H2PO4)2]2− ⊂ [H486]4+.

(C) The crystal structure of the complex [(H2P2O7)2]4− ⊂ [H486]4+.

(D) The crystal structure of the complex [(H3P3O10)2]4− ⊂ [H486]4+.

All anions encapsulated in the cavity are shown in space-filling form. Color code: C = gray, N = blue, O = red and P = yellow. Solvent molecules outside the cavities are omitted for clarity.
