制备了原型离子液体1-丁基-3-甲基碘化咪唑鎓[bmim]I的晶体，并确定了其空间群P2 1 2 1 2 1的晶体结构。丁基链具有正向和反式构型，并且只有一个阳离子H原子通过氢键与碘阴离子连接。涉及碘阴离子的弱氢键网络是[bmim]I的特征，这可能与在233 K下完成结晶的观察有关。
A crystal of l-butyl-3-methylimidazolium iodide [bmim]Ι, a prototype ionic liquid, has been prepared and its crystal structure has been determined at the space group P2 1 2 1 2 1 . The butyl-chain has gauche and trans configurations, and only one H atom of cation is linked to the iodide anion through a hydrogen bond. The weak hydrogen-bonded network involving the iodide anion is a characteristic feature of [bmim]I, which could be related to the observation that crystallization was accomplished under 233 K.
