(4). These acids were reacted with guanidinium carbonate to yield [+C(NH2)3][HCCSO3−] (5) and [+C(NH2)3][CH3CCSO3−] (6). Compounds 1–6 were characterized by spectroscopic methods, and the X‐ray crystal structures of the guanidinium salts were determined. The X‐ray results of 5 show that the guanidinium cations and organosulfonate anions associate into 1D ribbons through (8) dimer interactions, whereas
的HCCSO水解3森达3(1)和CH 3 CCSO 3森达3(2)导致炔磺酸HCCSO形成3 H⋅2.33ħ 2 O(3)和CH 3 CCSO 3 H·1.88 H 2 O(4)。这些酸用碳酸胍反应,得到[ + C(NH 2)3 ] [HCCSO 3 - ](5)和[ + C(NH 2)3 ] [CH3 CCSO 3 - (6)。化合物1 - 6通过光谱学方法进行了表征,并测定胍盐的X射线晶体结构。的X射线的结果5表明,胍鎓阳离子和阴离子有机磺酸结合成通过1D带(8)的二聚物的相互作用,而在这些离子的关联6是通过实现(8)和(6)的相互作用。5中的色带通过(8)二聚体相互作用和(12)环缔合成2D图纸,而6中的色带通过(6)和(8)二聚体相互作用和(14)环。化合物6表现出的单层堆积基序类似于在胍烷烃和芳烃磺酸盐中发现的基序,也就是说,炔基基团从一个碳带到另一个碳带交替排列。5
