摘　　要：Three-component framework of cucurbit[6]uril, 3-（1-methylimidazolium-3-yl）propane-l-sulfonate and boric acid has been constructed. The crystal structure reveals 1 ： 2 host-guest motif of cucurbit[6]uril and 3-（1-methyl- imidazolium-3-yl）propane-l-sulfonate, demonstrating both cation binding of imidazolium moiety and anion binding of sulfonate moiety for the first time. Incorporation of dimeric boric acid facilitates the formation of metal-free three-dimensional framework.Three-component framework of cucurbit[6]uril, 3-（1-methylimidazolium-3-yl）propane-l-sulfonate and boric acid has been constructed.
