Cucurbit[6]uril p-phenylenediammonium diiodide decahydrate inclusion complex

W.-H. Huang, P. Y. Zavalij and L. Isaacs

Abstract: The inclusion complex, C₆H₁₀N₂²⁺·2I^-·C₃₆H₃₆N₂₄O₁₂.10H₂O, displays a large ellipsoidal deformation of the cucurbit[6]uril skeleton upon complex formation. The cucurbit[6]uril molecule and the phenylenediammonium dication are each disposed about a center of inversion.
