Rhenium trioxynitrate is prepared by the reaction of ReO3Cl (produced by reacting rhenium trioxide and chlorine) and dinitrogen pentoxide:[1]
- ReO3Cl + N2O5 → ReO3NO3 + NO2Cl
The ReO3Cl can be replaced with rhenium heptoxide, however, this produces an impure product. This compound reacts with water to produce perrhenic acid and nitric acid.[1]
When heated above 75 °C, it decomposes to rhenium heptoxide, nitrogen dioxide, and oxygen:[1]
- 4 ReO3NO3 → 2 Re2O7 + 2 NO2 + O2
A graphite intercalation compound can be produced by reacting a mixture of rhenium trioxynitrate and dinitrogen pentoxide with graphite.[2]
X-ray diffraction and IR spectroscopic evidence rejects the formulations NO2+ReO4– or Re2O7·N2O5, but instead suggests a polymeric structure with a monodentate nitrate ligand.[1][3]
