摘要
The highest nitrogen-containing binary C-N anion, 5-azido-tetrazolate (CN7−), has attracted significant attention owing to its high-energy content. Due to its relative instability and high sensitivity, it is an ongoing challenge to develop more stable and less sensitive novel materials based on CN7−. Towards this goal, we have stabilized the CN7− anion without compromising its energetic performance by formation of its NH3OH+ salt containing an additional NH2OH molecule, [NH3OH][CN7][NH2OH] (2). It possesses the best detonation performance and the lowest mechanical sensitivity among all known CN7−-based materials. The structure-property relationship was elucidated through a careful investigation of the noncovalent interactions in the crystal lattice and the important role of the NH2OH moiety. In addition, the structurally related compound [NH3OH][CN7] (1) was also studied.
