(thiazole) bonded R22(8) molecular dimers by two homo-intermolecular hydrogen bonding interactions. N-(6-methoxybenzo[d]thiazol-2-yl)acetamide formed (amide)N-H…O (acid) & (acid)O-H…N (thiazole) interactions with the acetic acid, forming a R22(8) hydrogen-bonded ring by two hetero-intermolecular hydrogen bonding interactions.
通过将苯并噻唑与乙酸回流,可以合成三种不同的,与氢键相关的N-(苯并[d]噻唑-2-基)乙酰胺。组件的性质是苯并噻唑部分中取代基的特征。在N-(苯并[d]噻唑-2-基)乙酰胺中,水充当形成三个氢键的桥,是酰胺NH的受体,而酰胺和噻唑的羰基供体则由三种不同的N-(苯并[d]噻唑-2-基)乙酰胺分子。N-(6-甲基苯并[d]噻唑-2-基)乙酰胺通过两个同分子间氢键相互作用形成一个(酰胺)NH…N(噻唑)键合的R22(8)分子二聚体。N-(6-甲氧基苯并[d]噻唑-2-基)乙酰胺与乙酸形成(酰胺)NH…O(酸)和(酸)OH…N(噻唑)与乙酸相互作用,
