- There are three known varieties of Bi$_{4}$V$_{2}$O$_{11}$ (Villars, 2018):
- The sites we have labeled O-XXIV, O-XXV, O-XXVI, V-III, and V-IV are each only occupied 50% of the time in any one primitive cell.
- (Mairesse, 2003) describe the structure of $\alpha$–Bi$_{4}$V$_{2}$O$_{11}$ in the $A2$ setting of space group #5 with unique axis $c$. We describe it in our standard setting, $C2$ with unique axis $b$.
