- Below 670$^\circ$ this transforms into the $\alpha$–SnWO$_{4}$ structure (Jeitschko, 1972).
- SnWO$_{4}$ melts above 782$^\circ$C.
- The current sample was heated above 670$^\circ$C and rapidly quenched.
- The atoms in Sn$_{2}$Fe$_{3}$Cl occupy the same Wyckoff positions, but with different site occupations.
