Abstract The three crystal structures of β-sulfidocarbonyls 1, 2 and 3 synthesized from the reaction of acryl amide with cystiene, 1,2-dithiol and 1,3-dithiols, respectively, in water catalyzed by borax, have been determined at 273 K. The characteristic features of the structures are self-assembly through intermolecular hydrogen bonding leading to infinite chains of molecules in one direction, in addition
摘要 丙烯酰胺与胱氨酸、1,2-二硫醇和1,3-二硫醇在硼砂催化的水中反应合成的β-硫羰基1、2和3的三种晶体结构已在273 K下确定。 . 该结构的特征是通过分子间氢键自组装导致在一个方向上形成无限长的分子链,此外在垂直方向上堆叠这种分子链的层最终会产生 3D 的 β 褶皱片涉及晶格中 N-H⋯O、C-H⋯O 和 C-H⋯S 键的分子网络。
