A nitrogen-rich, polynitro energetic compound with an N, N-azo linkage, 1, 1′-azobis(3, 5-dinitropyrazole)(ABDNP), was synthesized using 3, 5-dinitropyrazole(DNP) as starting material via neutralization, N-amination and oxidative coupling reaction etc, and its structure was characterized by IR, ¹H NMR, ¹³C NMR, MS and elemental analysis. The effect of oxidizing agents on the coupling reaction were investigated. Results show that tert-butyl hypochlorite(t-BuOCl) is a better oxidizing agent with yield of ABDNP up to 43.5%. The physical-chemical and detonation performance of ABDNP were calculated by Gaussian 09 and VLW equation with density 1.94 g·cm^-3, detonation velocity 9309.0 m·s^-1 and detonation pressure 42.2 GPa, better than those of RDX.
