  • (Wyckoff, 1922) determined this approximate structure. In his paper, non-zero coordinates were $x_{2} = 1/4$ for the nitrogen (8c) atoms, $x_{3} = v$, where $v$ is somewhat less than 0.25, for the NH$_{3}$ (24d) molecules, and $x_{4} = y_{4} = 1/4, z_{4} = v'$, where $v'$ should not deviate far from 0. If we take these coordinates as written the space group becomes $Fm\overline{3}m$ #225 rather than Wyckoff's $Pa\overline{3}$ #205, so we adjusted $v$ and $v'$ slightly to put the system in his space group.
  • (Ewald, 1931) gave this the Strukturbericht designation $H61$, or $H6_{1}$ in later notation. (Hermann, 1937) moved it to $I1_{4}$ in their list of type descriptions, but no other volume of Strukturbericht refers to it at all. Accordingly, we will designate this structure by its original label.
  • This structure is an idealized appoximation to the true structure of Ni(NO$_{3}$)$_{2}$(NH$_{3}$)$_{6}$. (Bigoli, 1971) showed that the correct structure is trigonal, with space group $P\overline{1}$ #2.
