calculations and experimental data showed that all the studied molecules adopted flat conformations, but only in the case of three crystal structures were flat sheets observed. To assess the contribution of hydrogen and chalcogen bonds to the stabilization of the crystal structure, crystal lattice energy calculations were performed.
本文介绍了同时带有氢和硫属键供体的硫属二唑羧酸的晶体结构。所选分子的芳香族单元大小、硫属原子和/或核心结构中羧基的位置各不相同。其晶格中最常见的合成子是 R 2 2 (8) 自互补酸二聚体或四元 [Ch⋯N] 2环。还鉴定了硫属二唑部分与羧基相互作用的超分子合成子。 ESP计算和实验数据均表明,所有研究的分子均采用扁平构象,但仅在三种晶体结构的情况下观察到扁平片状。为了评估氢键和硫族键对晶体结构稳定的贡献,进行了晶格能量计算。
