Sodium perrhenate has been used as a precursor of rhenium nitrides (such as Re 3 N, Re 2 N, Re 3 N 2, ReN 2, ReN 3, ReN 4), which can be used as catalysts for ammonia synthesis and for hydro-denitrogenation. [4] It can be used to prepare Re 2 (CO) 10. [3]

Perrhenic acid is the chemical compound with the formula Re 2 O 7 (H 2 O) 2.It is obtained by evaporating aqueous solutions of Re 2 O 7.Conventionally, perrhenic acid is considered to have the formula HReO 4, and a species of this formula forms when rhenium(VII) oxide sublimes in the presence of water or steam.

Nylon 6,6 has a solubility parameter of 13.7 cal 1/2 cm −3/2, and ethanol is likely to be the best solvent of those tabulated. However, the latter is polar, and thus we should be very cautions about using just the Hildebrand solubility parameter to make predictions.
Rhenium is also able to make complexes with fullerene ligands such as Re 2 (PMe 3) 4 H 8 (η 2:η 2 C 60). One of the first transition metal hydride complexes to be reported was (C 5 H 5) 2 ReH. A variety of half-sandwich compounds have been prepared from (C 5 H 5)Re(CO) 3 and (C 5 Me 5)Re(CO) 3.
