Controllable explosion: fine-tuning the sensitivity of high-energy complexes

Tuning the sensitivity of energetic materials has always been a research topic of interest. A lot of attention has been paid on changing the ligands previously used in traditional high energy density materials (HEDMs). Recently, we have stepped further along this path by thinking from another angle, i.e., changing the metal centre. Herein, we report 4 transition metal complexes bearing the 1,5-diaminotetrazole ligand, which have similar structures but drastically different sensitivities. These differences are apparently due to the different metal centres used.
