Starting materials: Methanol, benzene, (C6F5C2H4NH3)2SnI4
Product: Red plate-like crystals
Description: Crystals of (2,3,4,5,6-FPEA)2SnI4 intercalated with benzene were prepared by mixing the base layered perovskite with methanol. Then an excess of benzene was added to the solution and the solution was stirred until it became homogenous and yellow. Then it sat in an inert atmosphere for a few days and red, plate-like crystals of the system formed.
Method: Single-crystal X-ray diffraction
Description: Data was collected with the Bruker SMART CCD diffractometer using 2.4 kW tube X-ray source (Mo Kα radiation).

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.
