Un oxyde de rhenium en relation de structure avec V2O5

The authors describe a rhenium oxide, Re2O5. It was revealed and investigated by means of transmission electron microscopy and single diffraction. The orthorhombic unic cell is related to the ReO3 cubic cell in terms of: b=c=ac= 3,747 A and a= 2 ac √2= 10,598 A. The crystal structure is explained from patterns, according to the structural scheme of Me2O5 and particularly to vanadium pentoxide structure. It is obvious that there exists a close relationship between them.
