Abstract Treatment of a mixture of isomeric N-ethyl-4(5)-nitro-1,2,3-triazoles with copper(II) chloride or copper(II) perchlorate was found to yield crystalline complexes with 1-ethyl-5-nitro-1,2,3-triazole (entz), namely [Cu(entz)2Cl2] or [Cu(entz)4(H2O)2](ClO4)2, respectively. The obtained complexes, being the rare examples of coordination compounds of vicinal nitrotriazoles, have been characterized
摘要 用氯化铜 (II) 或高氯酸铜 (II) 处理异构 N-乙基-4(5)-硝基-1,2,3-三唑的混合物,发现与 1-乙基-5-硝基-1,2,3-三唑 (entz),即分别为 [Cu(entz)2Cl2] 或 [Cu(entz)4(H2O)2](ClO4)2。所得配合物是邻位硝基三唑配位化合物的罕见例子,已通过X射线衍射和热法表征。两种化合物都呈现单核配合物,entz 通过杂环的 N3 原子配位。该配合物在氨水的作用下很容易分解,以高产率生成纯的1-乙基-5-硝基-1,2,3-三唑。络合和去络合反应的连续被证明是分离 1-乙基-5-硝基-1,2、
