Three distinct, hydrogen bond associated N-(benzo[d]thiazol-2-yl) acetamides were synthesized by refluxing benzothiazoles with acetic acid. The nature of the assemblies was characteristic to the substituent in the benzothiazole moiety. In N-(benzo[d]thiazol-2-yl)acetamide, water acts as a bridge for forming three hydrogen bonds, as an acceptor to amide NH, and donors to carbonyl of amide and thiazole nitrogen assembles of three different N-(benzo[d]thiazol-2-yl)acetamide molecules. The N-(6-methylbenzo[d]thiazol-2-yl)acetamide formed a (amide) N-H…N (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.

深入了解酰胺氢键合N-（苯并[d]噻唑-2-基）乙酰胺晶体的光物理性质。

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，
