Abstract: | The IR spectra of 3-amino-4-nitrofurazan (1) and 4-amino-4-nitroazoxyfurazan (2) in the crystalline state and in solutions in CH{in2}Cl{in2}, CCl{in4}, and MeCN have been studied. It was shown that both compounds exist in the solid state as self-associates, which are destroyed on dissolution in an organic solvent. Compouns1 and2 form associate complexes with MeCN, the energies of formation of which are –5 and –3 kcal mol{su–1}, respectively.Translated fromIzvestiya Akademii Nauk.
