Balancing the Energy and Sensitivity of Primary Explosives: Using Isomers to Prepare Energetic Coordination Compounds

Inorganic Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 23, 2025

The performance of energetic coordination compounds (ECCs) is influenced by their components and structure. Modifying the chemical structure ligands can balance detonation sensitivity. This study introduced Cu(3-PZCA)2(ClO4)2 (ECCs-1) Cu(2-IZCA)2(ClO4)2 (ECCs-2), using 3-PZCA 2-IZCA as ligands. ECCs-2, with a higher symmetry fewer nitrogen chains, showed highest thermal decomposition temperature (225 °C). Both ECCs displayed high mechanical sensitivity, ECCs-2 being slightly less sensitive (IS = 3 J, FS 8 N). They shared similar properties ignition capabilities, ECCs-1 having velocity (7.1 km·s-1) pressure (23.5 GPa). Initiation tests confirmed excellent DDT. theoretical mechanism suggests free radical reaction, explaining consistent ignition, initiation capabilities. A "SP–DM–DSC–MS–DA" structure–property relationship was established, providing foundation for studying Cu(ClO4)2-ECCs isomers.

Energetic coordination compounds (ECCs) show promising properties to be used as potential substitutes for highly toxic lead-containing primary explosives. The concept is combine the three building blocks: (i) ligand, (ii) transition metal, and (iii) anion, acting fuel, matrix, oxidizer (e.g., ClO4-, NO3-, ClO3-) or energetic component DN-, N3-, picrate, styphnate, trinitrophloroglucinate). By variation of ligands, complexes' can adjusted toward their desired performance sensitivities.
