Synthesis and structure of 3,4,5-triazidopyridine-2,6-dicarbonitrile possessing the record positive heat of formation

3,4,5-Triazidopyridine-2,6-dicarbonitrile, the first aromatic triazide with three adjacent azido groups in the ring, possessing the record positive heat of formation, was synthesized by azidation of 3,4,5-trichloropyridine-2,6-dicarbonitrile and characterized with X-ray analysis, thermogravimetry, differential scanning calorimetry and spectroscopic methods. © 2017
