Figure 5. Acyclic N-bridged tripodal anion receptor 10 and its anionic dimer complexes.

Figure 5

(A) Molecular structure of receptor 10.

(B) Single crystal X-ray structure of the complex [Cl2(H2O)2]2−⊂ [H10]+2.

(C) Single crystal X-ray structure of the complex [Br2(H2O)2]2−⊂ [H10]+2.

All anions and bridging water molecules encapsulated in the cavity of the dimeric capsules are shown in space-filling form. Color code: C = gray, N = blue, O = red, Cl = green and Br = brown. The counter cations and solvent molecules outside the cavities are omitted for clarity.
