Crystal structure of β′-Fe0.33V2O5

Abstract

Abstract Fe0.33V2O5 crystallizes in the monoclinic space group C2/m with a = 15.307(8) Å, b = 3.624(2) Å, c = 10.123(5) Å, β = 107.30(3)°, V = 536.12 Å3, and Z = 6. The structure was determined from single crystal X-ray diffraction data and it is related to the β-MxV2O5 structure type. There are some indications of partial cationic order between V4+ and V5+ within the three vanadium sites. Fe2+ occupies two crystallographic sites with tetrahedral and 3 + 1 coordination, respectively.
