摘要
对称四甲基六元瓜环(TMe Q[6])与钾离子(K+)在稀盐酸水溶液中相互作用形成配合物,用单晶-X射线衍射仪测试其晶体结构。测试结果表明,配合物形成以TMe Q[6]为"碗体",钾离子为"碗底"的"分子碗"结构,相邻配合物结构单元之间通过氢键或配位键连接形成一维超分子链。
A novel molecular bowl based on Tetramethyl Substituted Cucurbit[6]uril(TMeQ[6]) and patassium cation were synthe- sized in HC1 aqua and structurally characterized by single crystal X-ray diffractions. The crystal structure of the complex shows that two potassium cations covering one portal of TMeQ [6] and four water molecules were assembled in the cavity of TMeQ [6] to form a molecular bowl, the complex forms a new one-dimension (1D) supramolecular chain through hydrogen bonding or coordination in the crystal state.
