Energetic coordination polymers (ECPs) based on tetrazole N -oxides: green nitrogen-rich energetic complexes of variable dimensions.

In recent years, it has been demonstrated that the energetic properties of many tetrazole-containing compounds can be enhanced through the formation of the corresponding N -oxides. The introduction of N -O groups increases the oxygen balance of tetrazole compounds, while providing additional coordination sites and enriching the coordination modes between tetrazole compounds and metal ions. The introduction of O atoms alters the polarity of the substance from N to N -O, the packing and density increase and therefore the detonation velocity ( V D ) and pressure ( P ) also increase. Based on this, energetic coordination polymers (ECPs) with tetrazole N -oxides serving as ligands possess extremely high research value. In this paper, we aim to summarize the existing ECPs based on tetrazole N -oxides briefly and discuss their advantages, emphasizing their excellent stability and application prospects.
