Starting materials: HI, SnI2, C6F5C2H4NH3I, toluene
Product: Red plate-like crystals
Description: Crystals were grown by slowly cooling a solution of HI, C6F5C2H4NH3I, and SnI2. SnI2 was added first, then the organic salt, and then HI. The solution was mixed and heated to 94 degrees Celsius to completely dissolve SnI2. The solution was then cooled at 3 degrees per hour until 0 degrees was reached, resulting in the formation of red crystals. The crystals were filtered in an inert atmosphere and recrystallized twice from a solution of methanol and toluene.
Method: Thermogravimetric Analysis (TGA)
Description: TGA was performed with a TA Instruments TGA-2950 on the crystals that were isothermally purged in a nitrogen atmosphere at ambient temperature for 20 minutes. The temperature was then increased at a constant rate of 5 degress Celsius per minute up to 600 degrees.

Method: Differential Scanning Calorimetry (DSC)
Description: DSC was performed with a TA Instruments MDSC-2920. A heating rate of 5 degrees per minute weas used and the temperature scale was calibrated using the indium melting transition. This is power-compensated DSC where the heating rate and power supply is constant.
