Preparation and Explosive Properties of Tetraamminebis(3,5-Dinitro-1,2,4-Triazolato-N¹)Copper(II)

ABSTRACT

The synthesis of tetraamminebis(3,5-dinitro-1,2,4-triazolato-N¹)copper(II) is reported along with its physical and sensitivity properties as well as crystal structure. In addition, the detonation velocity and CJ pressure have been determined at 0.5 inch diameter.

Keywords:

• energetic coordination compounds
• 3,5-dinitro-1,2,4-triazolate
• copper(II)
