  • The structure of AgMnO4 was originally determined by (Sasvári, 1938) and refined by (Boonstra, 1968). In particular, Boonstra found that the actual positions of the Ag and Mn atoms were switched compared to the structure found by Sasvári. As the lattice constants remain approximately the same and there was no change in the space group or the occupied Wyckoff positions, we use the Boonstra structure to define Strukturbericht designation H09.
  • Boonstra gave the structure in setting $P21/n$ of space group #14. We used FINDSYM to translate the structure to the standard $P2_{1}/c$ setting. This included a redefinition of the primitive vectors of the lattice.

Simple Monoclinic primitive vectors:

\[ \begin{array}{ccc} \mathbf{a}_1 & = & a \, \mathbf{\hat{x}} \\ \mathbf{a}_2 & = & b \, \mathbf{\hat{y}} \\ \mathbf{a}_3 & = & c \cos\beta \, \mathbf{\hat{x}} + c \sin\beta \, \mathbf{\hat{z}} \\ \end{array} \]
