Rhenium trioxynitrate, also known as rhenium(VII) trioxide nitrate, is a chemical compound with the formula ReO3NO3.
It is a white solid that readily hydrolyzes in moist air.
[1] Rhenium trioxynitrate is prepared by the reaction of ReO3Cl (produced by reacting rhenium trioxide and chlorine) and dinitrogen pentoxide:[1] The ReO3Cl can be replaced with rhenium heptoxide, however, this produces an impure product.
[1] When heated above 75 °C, it decomposes to rhenium heptoxide, nitrogen dioxide, and oxygen:[1] 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.
