- This is the stable structure of iron sulfide below 242K. Above that temperature it is in the zincblende ($B3$) structure. (Wintenberger, 1978).
- This data was taken at 81K. We follow (Villars, 2016) and rearrange the axis, as well as reversing the positions of the iron and sulfur atoms.
\[ \begin{array}{ccc}
\mathbf{a_{1}}&=&\frac{1}{2}b \,\mathbf{\hat{y}}+\frac{1}{2}c \,\mathbf{\hat{z}}\\\mathbf{a_{2}}&=&\frac{1}{2}a \,\mathbf{\hat{x}}+\frac{1}{2}c \,\mathbf{\hat{z}}\\\mathbf{a_{3}}&=&\frac{1}{2}a \,\mathbf{\hat{x}}+\frac{1}{2}b \,\mathbf{\hat{y}}
\end{array}\]
