with four cations and two anions in the asymmetric unit. The hydroxy group of the cation of 1s is observed in two R/S disorder positions. The crystals of these two salts display similar supramolecular architectures (i.e. two‐dimensional networks), built mainly by intermolecular N+—H…Oδ− and O—H…Oδ− hydrogen bonds, where `δ−' represents a partial charge. The succinate anions are engaged in hydrogen
氨基链烷醇和芳氧基烷基衍生物被称为潜在的抗惊厥药。两种新的盐,即双(R,S)‐ N- [2-(2,6-二甲基苯氧基)乙基] -1-羟基丙烷-2-铵}琥珀酸盐(1s),C 13 H 22 NO 2 + ·0.5 C 4 H 4 O 4 2−和bis (S)‐(+)‐ N‐ [2-(2,6-二甲基苯氧基)乙基] ‐1‐羟基丙烷‐2‐}}琥珀酸酯(2s),C 13 H 22 NO 2 + ·0.5C 4 H 4 O 4 2−通过单晶X射线衍射制备并表征。N原子通过从琥珀酸转移质子而质子化。盐1s在P 2 1 / n的空间群中以一个阳离子和一半阴离子在一个反对称中心上结晶,而(2s)在P 2 1的空间群中以四个阳离子和两个阴离子在非对称单元中结晶。。在两个R / S无序位置观察到1s阳离子的羟基。这两种盐的晶体显示出相似的超分子结构(即二维网络),主要由分子间的N + -H… Oδ-和O-H
