  • Tutton Salts have the form AB$_{2}$(SO$_{4}$)$_{2}$·6H$_{2}$O, where A is a divalent ion and B is a monovalent ion. (Hermann, 1937) formally lists Mg(NH$_{4}$)$_{2}$(SO$_{4}$)$_{2}$·6H$_{2}$O as the prototype, but notes that one may have other monovalent metals in place of NH$_{4}$ and divalent [metals] in place of Mg. We choose the Cu(NH$_{4}$)$_{2}$(SO$_{4}$)$_{2}$·H$_{2}$O as the prototype because (Brown, 1969) were able to locate all of the hydrogen ions in agreement with expectation, i.e., H$_{2}$O molecules have properly bent H-O bonds, and the hydrogen atoms in the ammonium ion form a tetrahedron around the nitrogen atom.
  • The atomic positions were originally given in the $P2_1/a$ setting of space group #14. We used FINDSYM to convert this to the standard $P2_1/c$ setting. This resulted in the $a$ and $c$ axes being swapped.
