  • Chrysotile is more commonly known as white asbestos. Chrysotile sheets typically curl into tubular fibers and the crystal structure is difficult to determine. (Yada, 1967) has a partial list of the experiments performed to determine this structure. The current structure was given the Strukturbericht designation $S4_{5}$ by (Hermann, 1937). It doubles the unit cell of our other chrysotile structure, by (Falini, 2004) and includes an inversion site.
  • The structure was originally given in the $I2/m$ setting of space group #12. We used FINDSYM to place it in the standard $C2/m$ setting.
