The synthesis, structure, and reactivity of several 1,2,4-triazolo[4,3-b][1,2,4]triazole derivatives have been studied. Structures have been established throughout a careful carbon-13 NMR study, and for the most unusual one (inner salt of 2-methyl-3-methylthio-6-phenyl-7H-1,2,4-triazolo[4,3-b][1,2,4]triazolium hydroxide) by X-ray crystallography: the space group is P21/c, the cell constants are a=12
已经研究了几种 1,2,4-三唑并 [4,3-b][1,2,4] 三唑衍生物的合成、结构和反应性。在仔细的碳 13 核磁共振研究中已经建立了结构,对于最不寻常的结构(2-甲基-3-甲硫基-6-苯基-7H-1,2,4-三唑并[4,3-b ][1,2,4]氢氧化三唑鎓)通过 X 射线晶体学:空间群为 P21/c,电池常数为 a=12.6939(5), b=16.0936(6), c=12.0239(5) 和β=107.247(3)°,Z=8。S-甲基基团指向在+/-syn 构象处的五元环的融合。氮杂戊烯部分在其平面上具有取代基的第一个原子,并且在两个独立的分子中,6-苯环与其成-26.7°和-4.3°的角。
