Other compounds with this structure
Ba$_{3}$Co$_{3}$P$_{2}$TeO$_{14}$, Ca$_{3}$NbGa$_{3}$Si$_{2}$O$_{14}$, Ca$_{3}$Ga$_{2}$Ge$_{4}$O$_{14}$ (langasite), La$_{3}$Ga$_{3}$(Ga, Si)$_{2}$GaO$_{14}$, La$_{3}$Ga$_{5}$SiO$_{14}$, Pb$_{3}$Mn$_{3}$P$_{2}$TeO$_{14}$, Ba$_{3}$TeCo$_{3}$P$_{2}$O$_{14}$, Pb$_{3}$TeCo$_{3}$P$_{2}$O$_{14}$, Pb$_{3}$TeCo$_{3}$V$_{2}$O$_{14}$
- Some authors use langasite, Ca$_{3}$Ga$_{2}$Ge$_{4}$O$_{14}$, as the prototype for this structure, however in langasite the (1a) and (3f) Wyckoff positions are a mixture of gallium and germanium atoms (Dudka, 2013). None of the Wyckoff positions in dugganite are disordered, so we use it as the prototype.
