  • This is not the version of the structure given in (Hermann, 1939) as Strukturbericht $E3_{3}$. That structure was determined by (Brasseur, 1939). We have no clear indication as to which structure is correct.
  • The positions of the hydrogen atoms in the water molecules were not determined, so we only give the positions of the oxygen atoms (labeled as H2O).
  • (Kamenar, 1962) gives the crystal structure and atomic positions in the $Pbnm$ setting of space group #62. We have used FINDSYM to show the structure in the standard $Pnma$ setting.

Simple Orthorhombic primitive vectors:
