Chemical compound
Rhenium trioxynitrate , also known as rhenium(VII) trioxide nitrate , is a chemical compound with the formula ReO3 NO3 . It is a white solid that readily hydrolyzes in moist air.[ 1]
Preparation and properties
Rhenium trioxynitrate is prepared by the reaction of ReO3 Cl (produced by reacting rhenium trioxide and chlorine ) and dinitrogen pentoxide :[ 1]
ReO3 Cl + N2 O5 → ReO3 NO3 + NO2 Cl The ReO3 Cl 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 ReO3 NO3 → 2 Re2 O7 + 2 NO2 + O2 A graphite intercalation compound can be produced by reacting a mixture of rhenium trioxynitrate and dinitrogen pentoxide with graphite.[ 2]
Structure
X-ray diffraction and IR spectroscopic evidence rejects the formulations NO2 + ReO4 – or Re2 O7 ·N2 O5 , but instead suggests a polymeric structure with a monodentate nitrate ligand.[ 1] [ 3]
