title: Cucurbit[6]uril p-xylylenediammonium diiodide deca-hydrate inclusion complex.
abstract: The title inclusion complex, C(36)H(36)N(24)O(12)·C(8)H(14)N(2) (2+)·2I(-)·10H(2)O, displays a large ellipsoidal deformation of the cucurbit[6]uril (CB[6]) skeleton upon complex formation. The benzene ring of the cation is rotationally disordered between two orientations in a ratio of 3:1. The solvent H(2)O mol-ecules form a hydrogen-bonded network by inter-action with the carbonyl groups of CB[6] and the I(-) counterions. The crystal studied exhibited non-merohedral twinning. Both CB[6] and the cation are centrosymmetric.
