High-dimensional energetic coordination compounds (ECCs) exhibit high stability and low sensitivity owing to their complex network structure, making them valuable in functional materials such as combustion catalysis insensitive detonating explosives. Four ECCs, [Co(DNBT)(H2O)4]n (ECC-1), [Ni(DNBT)(H2O)4] (ECC-2), [Cu2(DNBT)2(H2O)3MeOH] (ECC-3), [Zn(DNBT)(H2O)4] (ECC-4), were synthesized by modifying the metal centers using 5,5'-dinitro-4H,4'H-3,3'-bi(1,2,4-triazole) (DNBT) ligands. After changing solution environment adding auxiliary ligand 4H-1,2,4-triazol-4-amine (4-ATr), we obtained three ECCs with similar structures once again: [Co2(DNBT)2(4-ATr)3(H2O)2] (ECC-5), [Ni2(DNBT)2(4-ATr)3(H2O)2] (ECC-6), [Cu2(DNBT)2(4-ATr)3] (ECC-7). fewer water molecules chosen for laser ignition detonation tests evaluate laser-induced capabilities, indicating potential applications initiators. The response behavior differs between [Cu2(DNBT)2(4-ATr)3]. exhibits excellent response, a minimum initiation energy of 11 mJ short lengthy delay 2.31 ms, whereas is less sensitive under same conditions. Theoretical calculations at different power densities indicate that possesses more efficient photothermal conversion. This reduced may stem from presence water. charge transfer these thoroughly analyzed through theoretical structural studies.
