Abstract

It is an enormous challenge to construct high-energy-density materials meeting simultaneously requirements of high energy and excellent stability. In this work, the reaction of a Ag(I) ion with a nitrogen-rich ligand, 1H-tetrazole-5-acetic acid (H2tza), leads to a novel Ag7-cluster metal–organic framework, [Ag7(tza)3(Htza)2(H2tza)(H2O)] (1), with remarkable high-energy content, stability, and insensitivity. Dramatically, the heating-dehydrated process of 1 produces a new stable energetic material, [Ag7(tza)3(Htza)2(H2tza)] (1a), which features superior energy and undiminished safety performance compared to those of 1.
