Synthesis and characterization of 3,4,5-triamino-l,2,4-triazolium and 1-methyl-3,4,5-triamino-l,2,4-triazolium iodides

Abstract

3,4,5-Triamino-l,2,4-triazolium iodide (1) was obtained in good yield and purity and characterized using vibrational (IR, Raman) and multinuclear NMR spectroscopy (1H, 13C, 15N), EA, MS, DSC, and X-ray crystallography. The compound was synthesized by two different methods rendering two different polymorphs (α and β) as proved by X-ray measurements, vibrational spectroscopy and DSC. l-Methyl-3,4,5-triamino-l,2,4- triazolium iodide (2) was synthesized by reaction of guanazine with methyliodide and fully characterized by the same techniques mentioned above. Both compounds showed to be suitable starting materials for the synthesis of guanazinium salts of energetic interest. © 2008 WILEY-VCH Verlag GmbH & Co. KGaA,.
