NMR spectroscopic studies show that Tryller's and Schmitz's compounds have furoxan ( 3 ) and 1,4,2,5‐dioxadiazine ( 11 ) structures, respectively. Combined NMR spectroscopy and X‐ray crystallography show that the products obtained by action of dinitrogen tetroxide and 5% sodium hydroxide on Tryller's compound have furazano[3,4‐ d ]pyridazine 1,5,6‐trioxide and furazano[3,4‐ d ]pyridazine 5,6‐dioxide structures 5 and 8 , respectively. They also show that the product obtained by action of dinitrogen tetroxide on Schmitz's compound has a dinitroethyl‐1,4,2,5‐dioxadiazine structure 12 .
