Two energetic metal-organic frameworks (MOFs), Co-ANTA and Zn-ANTA, are synthesized from 5-amino-3-nitro-1H-1,2,4-triazole (ANTA) and exhibit superior oxygen balance, density, and thermal stability compared to ANTA. The superior oxygen balance is achieved through a combination of hydroxide ligands and deprotonated linkers. Although the materials are isostructural and have similar density, oxygen balance, and sensitivity to heat, their impact sensitivities are significantly different. Similar to ANTA, Zn-ANTA is fairly insensitive to impact. By contrast, the impact sensitivity of ANTA is increased significantly after coordination polymerization with cobalt. The disparate impact sensitivities of the compounds might be attributed to the different electronic configurations of the metal ions constituting the frameworks.
通过5-氨基-3-硝基-1H-1,2,4-三唑（ANTA）合成了两种具有高能量的金属有机框架材料（MOF），即Co-ANTA和Zn-ANTA，与ANTA相比，它们表现出优异的氧平衡、密度和热稳定性。优异的氧平衡是通过氢氧化物配体和去质子化连接体的组合实现的。尽管这些材料是同构的，并且具有相似的密度、氧平衡和热敏感性，但它们的撞击感度却有显著差异。与ANTA相似，Zn-ANTA对撞击相当不敏感。相比之下，ANTA与钴配位聚合后，其撞击感度显著增加。这些化合物不同的撞击感度可能归因于构成框架的金属离子的不同电子构型。
