Gallium complexes of bis-thiosemicarbazones were prepared and characterized using NMR and X-ray crystallography. Formation of a gallium nitrate complex was proven by NMR spectroscopy. Surprisingly, this complex was found to convert on standing to a new hydroxido-bridged di-gallium complex. The X-ray crystal structure of the digallium complex is described. Similarly, a triazene compound was formed during the preparation of the gallium complex comprising a tetraphenyl unit in the bis-thiosemicarbazone structure. We propose a mechanism for the formation of both the di-gallium species as well as triazene compound in solution. The lattice parameters for the digallium complex is as follows: a: 17.6854(13) Å, b:16.6492(7) Å, c: 21.4659(14) Å, β = 112.383(8)°.Graphical AbstractGallium complexes of bis-thiosemicarbazones were prepared and were found to convert to a new hydroxido-bridged di-gallium complex

NMR、X 射线晶体结构研究和新型二镓配合物和 5-Methoxy-4,5,6-triphenyl-4,5-dihydro-1,2,4-triazene-3(2H) 的形成机制-硫酮

使用 NMR 和 X 射线晶体学制备并表征了双缩氨基硫脲的镓配合物。硝酸镓络合物的形成由核磁共振光谱证实。令人惊讶的是，发现该复合物在静置时转化为新的羟基桥连二镓复合物。描述了二镓配合物的 X 射线晶体结构。类似地，在制备在双-氨基硫脲结构中包含四苯基单元的镓络合物期间形成三氮烯化合物。我们提出了一种在溶液中形成二镓物种和三氮烯化合物的机制。二镓配合物的晶格参数如下：a：17.6854(13) Å，b：16.6492(7) Å，c：21.4659(14) Å，β = 112.383(8)°。
