All of the synthetically accessible symmetric tetranitro-3,3'-bipyrazoles were prepared. On their basis, a method was developed for the synthesis of 4,4'-dinitro-1H, 1'H-[3,3'-bipyrazole]-5,5'-diamine and its nitration was studied.

The key to successfully designing highperformance and insensitive energetic compounds for practical applications is through adjusting the molecular organization including both fuel and oxidizer. Now a superior hydrogen -free 5/6/5 fused ring energetic material, 1,2,9,10-tetranitrodipyrazolo[1,5-d:5',1'-f][1,2,3,4]tetrazine (6) obtained from 4,4',5,5'-tetranitro-2H,21H3,3'-bipyrazole (4) by N-amination and N-azo coupling reactions is described. The structures of 5 and 6 were confirmed by single crystal X-ray diffraction measurements. Compound 6 has a remarkable room temperature experimental density of 1.955 g cm(-3) and shows excellent detonation performance. In addition, it has a high decomposition temperature of 233 degrees C. These fascinating properties, which are comparable to those of CL-20, make it very attractive in high performance applications.

family of 3,3′‐bipyrazole‐based energetic compounds having C‐NO2/N‐NO2 functionalities was synthesized by using various nitrating conditions. These nitro derivatives of bipyrazole are significantly more dense and energetic compared to the corresponding nitropyrazole analogues while maintaining the desired thermal stability and sensitivity. Depending on the number and nature of energeticnitrogroups (C‐NO2/N‐NO2)
