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.
