presence of a strong intermolecular N-H•••O interaction. In case of 7, the possibility of such an interaction is obviated by the formation of an intramolecular N-H•••O hydrogen bond. An additional feature of the crystal packing for 1—6 is the significant roles that C—H•••π contacts play in generating three dimensional networks. In contrast for 7, the intramolecular N—H•••O hydrogen bond precludes the formation
在这项研究中,我们调查了一系列的七个N-(取代的苯基)-2-萘酰胺中存在的不同分子间相互作用的性质和特征。七个结构包括通过酰胺桥连接至N-结合的苯基,1或取代的苯环3-7,或在2的情况下为环己烷环的2-萘环系统。除了邻硝基衍生物7以外,所有其他晶体的堆积都有一个共同的特征,即存在强烈的分子间NH•••O相互作用。在7的情况下,通过分子内NH···O氢键的形成消除了这种相互作用的可能性。1–6晶体包装的另一个特点是C•H•••π接触在生成三维网络中起着重要作用。相反,对于7
