α'-NaV₂O₄F crystallizes in the orthorhombic system with parameters a = 11.318 Å, b = 3.609 Å, c = 4.802 Å and space group D¹³/2h Pmmn. The sodium atoms are inserted between (V₂O₄F) [n-layers, charged 2n⁻]. The vanadium atoms are at the center of anionic square pyramids. The structural relationships between α'-Na V₂O₄F, V₂O₅, α and α'-NaₓV₂O₅ are determined.NaV₂O₄Fα' cristallise dans le système orthorhombique avec les paramètres a = 11,318 Å, b = 3,609 Å, c = 4,802 Å et le groupe spatial D¹³/2h, Pmmn. Le réseau est formé de [n-]feuillets (V₂O₄F) [chargés 2n⁻] entre lesquels s'insèrent les atomes de sodium. La vanadium est au centre d'une pyramide à base carrée formée par les anions. Les auteurs établissent les relations structurales entre le...
