A novel N–N bond cleavage in 1,5-diaminotetrazole: synthesis and characterization of 5-picrylamino-1,2,3,4-tetrazole (PAT)

Abstract

The reaction of 1,5-diaminotetrazole with picryl chloride (PiCl) forms 5-picrylamino-1,2,3,4-tetrazole (PAT) rather than the expected 1-picrylamino-5-amino-1,2,3,4-tetrazole or 5-picrylamino-1-amino-1,2,3,4-tetrazole. The structure of PAT was confirmed by single-crystal X-ray diffraction. Some of the energetic properties of the synthesized compound were also studied.
