Of the two tautomeric isomers of 1,2,4-triazole, 1,2,4-triazacyclopenta-3,5-diene and 1,2,4-triazacyclopenta-2,5-diene, the former was isolated as a 1:1 complex with the title host compound. X-Ray analysis of the complex reveals that the two molecular components are linked by hydrogen bonds with the triazole molecules lying in channels running parallel to the b axis, cutting a near O and c near 1/4.
在1,2,4-三氮唑的两个互变异构体中,1,2,4-三氮杂环戊-3,5-二烯和1,2,4-三氮杂环戊-2,5-二烯,前者与标题中的主化合物以1:1的比例分离。对复合物的X射线分析显示,两个分子成分通过氢键与三氮唑分子相连,三氮唑分子位于与b轴平行的通道中,切割了接近O和接近1/4的c。
