1,1′-Azobis-1,2,3-triazole: A High-Nitrogen Compound with Stable N8 Structure and Photochromism

Treatment of 1-amino-1,2,3-triazole with sodium dichloroisocyanurate led to isolation of 1,1'-azobis-1,2,3-triazole, which was well characterized. Its structure was determined by X-ray crystallographic analysis, and its thermal stability and photochromic properties were investigated.
