Abstract

Abstract : Through introducing nitro groups, a high-nitrogen–oxygen compound (4 ) was prepared. The OBco of compound 4 was improved to the value of zero, and it also exhibits good detonation performance (9018 m s −1 and 34.5 GPa). Abstract : In this study, an azido-based compound 4, N, N ′-methylenebis( N -(4-azido-1, 2, 5-oxadiazol-3-yl)nitramide), was synthesized and fully characterized. The crystal structure of 4 was determined for the first time to investigated the structure–performance relationship. Material 4 exhibited compact face-to-face and wavelike stacking. The introduction of nitro groups resulted in compound 4 having a zero oxygen balance based on carbon monoxide, which was out of the ordinary for azido-based materials. Such an excellent crystal arrangement and oxygen balance provided compound 4 with a better detonation performance ( D : 9018 m s −1 ; P : 34.5 GPa), which indicated its application as a promising high-energy-density material.
