Nitrogen‐rich 6‐(3,5‐Dimethylpyrazol‐1‐yl)‐3‐(2,4,6‐trinitro‐anilino)‐1,2,4,5‐tetrazin: Synthesis, Crystal Structure and Thermal Property

6‐(3,5‐Dimethylpyrazol‐1‐yl)‐3‐(2,4,6‐trinitroanilino)‐1,2,4,5‐tetrazin ( 1 ) has been synthesized and characterized by 1 H NMR, MS, elemental analysis, infrared spectra and thermal analyses. The crystal structure was determined by X‐ray diffraction method. 1 is crystallized in P 21 /c space group of monoclinic crystal system, and exhibits good physical properties, such as high densities (>1.55 g·cm −3 ) and good thermal stabilities ( T d >220 °C). The intrermolecular hydrogen bonds construct the P ‐ and M ‐helices from organic molecules and may contribute to the high melting points.
