| Abstract: | A supramolecular assembly based on cucurbituril(Q6]) andZn(H2O)6]2 was synthesized and structurally characterized by single-crystal X-ray diffractions.The crystal structure of this complex showed that a dioxane molecule was included in the cavity of Q6],and the transition metal ion Zn2 was coordinated six water molecules and located at the portals between two Q6] to form the molecular encapsulates.Through the hydrogen bonds formed with the coordinated water molecules with Zn cation and the portal carbonyl oxygen of the Q6],a one dimensional supramolecular chain of alternating octahedral and Q6] molecules was formed. |
