Starting materials: Tin (II) iodide, methylammonium iodide, HI (aq), argon, nitrogen
Product: Powder
Description: Dissolve tin(II) iodide (2.235 g, 6 mmol) in flowing argon at 70°C in 4 ml of a concentrated (57% by weight) aqueous HI solution. Dissolve methylammonium iodide (6 mmol) at room temperature in 1.0 ml of concentrated aqueous hydriodic acid and immediately add to the tin(II) iodide solution (after allowing it to cool). Rinse the methylammonium tube using two additional 0.5-ml portions of hydriodic acid and add to the test tube containing the product, which at all times was kept in an inert atmosphere of flowing argon. Maintain the product in the hydriodic acid solution for 15 min at room temperature, with periodic agitation of the solution, and filter under flowing dry nitrogen gas. Dry powder under vacuum at room temperature and store in an argon-filled glovebox, with oxygen and water levels maintained below 1 ppm.
Comment: Similar procedure as MASnI3 in D. B. Mitzi, C. A. Feild, Z. Schlesinger, and R. B. Laibowitz, J. Solid State Chem. 114, 159 (1995).
Method: Powder X-ray diffraction

Starting materials: Tin (II) iodide, formamidine acetate, HI (aq), argon, nitrogen
Product: Black powder
Description: Dissolve tin(II) iodide (2.235 g, 6 mmol) in flowing argon at 70°C in 4 ml of a concentrated (57% by weight) aqueous HI solution. Dissolve formamidine acetate (0.6246 g, 6 mmol) at room temperature in 1.0 ml of concentrated aqueous hydriodic acid and immediately add to the tin(II) iodide solution (after allowing it to cool), leading to a thick black precipitate. Rinse the formamidinium tube using two additional 0.5-ml portions of hydriodic acid and add to the test tube containing the product, which at all times was kept in an inert atmosphere of flowing argon. Maintain the product in the hydriodic acid solution for 15 min at room temperature, with periodic agitation of the solution, and filter under flowing dry nitrogen gas. Yield was approximately 75% of the theoretical yield. Dry black powder under vacuum at room temperature and store in an argon-filled glovebox, with oxygen and water levels maintained below 1 ppm.
Comment: Single crystal also made. Similar procedure as MASnI3 in D. B. Mitzi, C. A. Feild, Z. Schlesinger, and R. B. Laibowitz, J. Solid State Chem. 114, 159 (1995).
