N2 - Overcoming detonation performance constraints and achieving suitable mechanical sensitivity in energetic materials present profound challenges. Using regional isomerization, we strategically introduced high-energy structures into pyrazole rings and synthesized a new ligand, namely 1-amino-1H-pyrazole-5-carbohydrazide (1-APZ-5-CA), and its corresponding complex, denoted [Ag(1-APZ-5-HCA)(ClO4)2]n (ECPs-1). ECPs-1 capitalizes on a dual structural framework, comprising an ionic salt and a complex, resulting in enhanced [ClO4−] content, an elevated oxygen balance constant (+3.56%), remarkable thermal stability (Td = 225 °C), and excellent resistance to mechanical stimuli (IS = 8 J, FS = 64 N). Comprehensive testing, encompassing traditional ignition assessments and laser-based ignition experiments, unequivocally underscores the outstanding explosive initiation capabilities of ECPs-1 (P = 40 W, τ = 2 ms, E = 80 mJ).
