  • This is a quinary form of K$_{3}$Na(SO$_{4}$)$_{2}$. The ICSD lists K$_{3}$Na(SO$_{4}$)$_{2}$ as the structure type. We arbitrarily chose Na$_{2}$BaMn(VO$_{4}$)$_{2}$ as the prototype structure for the five-element form.
  • Na$_{2}$BaMn(VO$_{4}$)$_{2}$ can also be found in a monoclinic form (Sanjeewa, 2019).
  • K$_{2}$RbSc(PO$_{4}$)$_{2}$ and Na$_{2}$BaMn(VO$_{4}$)$_{2}$ occupy the same Wyckoff positions in space grop $P\overline{3}m1$ #164, but their AFLOW mismatch (Hicks, 2018) is sufficiently large (0.35) that we place them in two different prototypes. The structures are generated by the same symmetry operations with different sets of parameters (--params) specified in their corresponding CIF files.
