  • There are three known varieties of Bi$_{4}$V$_{2}$O$_{11}$ (Villars, 2018):
    • $\alpha$, the ground state structure, stable up to 450°C,
    • $\beta$, stable between 450°C and 555°C (this structure), and
    • $\gamma$, stable from 555°C up to the melting point at 880°C.
  • The data for this structure was taken at 550°C.
  • Several of the Wyckoff positions listed here are only partially occupied: V-I: 25%, V-II: 50%, and O-IV 75%.
  • (Mairesee, 2003) describe this structure in the $Amam$ setting of space group #63. We used FINDSYM to transform this to the standard $Cmcm$ setting.
