Starting materials: phenylethylammonium iodide (PEAI), tin (II) iodide (SnI2), gamma-bytrolactone (GBL)
Product: Red plate-like crystals
Description: Single crystals of were obtained by dissolving stoichiometric amounts of the organic salt and SnI2 in gamma-bytrolactone (GBL) (0.1 M), and then performing vapor diffusion of chloroform and chlorobenzene.

Method: Single-crystal X-Ray Diffraction
Description: A Bruker Quest diffractometer with kappa geometry, I-μ-S microsource X-ray tube (Cu Kα radiation, λ = 1.54178 Å), Photon2 CMOS area detector, and multilayer mirror for monochromatization was used. Data was scanned and corrected with APEX3, space groups were solved using XPREP in SHELXTL

Starting materials: HI, H3PO2, anhydrous ethanol, SnI2, organic cation iodide salt
Product: Dark plate-like crystals
Description: Stoichiometric ratios of purified SnI2 and the organic cation iodide salt were added to either an HI or ethanol solution in an inert atmosphere. The solids were fully dissolved by raising the ethanol solutions to 65 degrees Celsius and the HI solutions to 75 degrees. The solutions were then cooled at the rate of 1.5 degrees per hour until 5 degrees was reached, over which time crystals precipitated.
Method: Single-crystal X-ray diffraction
Description: Data were recorded using a Rigaku R-AXIS rapid imaging plate diffractometer with graphite-monochromated Mo Kα radiation (λ = 0.71069 Å).

Starting materials: PEAI, SnI2, HI, H3PO2
Product: Single crystals of 2D tin halide perovskites. Thin flakes were then exfoliated from the single crystals.
Description: Single crystals synthesized by slow cooling method. Growth solution prepared with 0.16mmol PEAI, 0.40mmol SnI2, 2mL HI, and 0.2mL H3PO2 in a sealed glass vial and placed in a muffle furnace and heated until completely dissolved. Solution cooled to room temperature at a rate of 2°C/hour. Crystals were then dried and stored in a nitrogen glove box.
Method: Single crystal X-ray diffraction
Description: PXRD performed by Bruker D8 Advance instrument scanning at 0.02° per step with a copper target. All single crystals were analyzed using a Bruker AXS D8 Venture diffractometer with a high-intensity diamond Cu/Mo hybrid dual-microfocal x-ray tube. All data collecting and processing was completed using APEX4 software. Full matrix least squares against F2 method was used for further refinement of structures.
