| α: | 90° |
| β: | 90° |
| γ: | 90° |
Starting materials: Lead acetate, HI (aq., 57 wt%), CH3NH2 (aq., 40%)
Product: Yellow MAPbI3 thin film (10 nm grain size)
Description: Dissolve 2.5 g of lead acetate (Sigma) in 10 mL hydroiodic acid (aq., 57 wt%, Sigma) in a 50 mL round bottom flask and heat to 100 °C in an oil bath. Add 0.597 g of CH3NH2 (aq., 40%, Sigma) dropwise to a further 2 mL of hydroiodic acid kept at 0 °C in an ice bath under stirring. Add the methylammonium iodide solution to the lead acetate solution and cool over two hours to 46 °C, affording a black precipitate. Filter and dry the black precipitate for 12 h at 100 °C. Average yield was 3.1 g, 75.2%. Repeat until 8 g of product has been obtained.
Comment: MAPbI3 was prepared according to the method of A. Poglitsch and D. Weber, J. Chem. Phys., 1987, 87, 6373–6378. CIF file: Fachinformationszentrum Karlsruhe, 76344 Eggenstein-Leopoldshafen (Germany), CSD 428898
Method: Powder neutron diffraction
Description: Data were collected using the D20 instrument at the ILL Grenoble operating in high take-off angle, higher resolution mode. 8 g of finely ground MAPbI3 was placed in a 7 mm diameter vanadium can. Data were collected for 90 minutes at 100 K. Raw diffraction data were corrected against detector efficiency and analysed using the GSAS/EXPGUI program suite; structure refinements for the long data collections at 100, 180 and 350 K were undertaken as described in the ESI. Refer to a,b,c, space group from ESI Table S1.1, volume from Garnett PRL, Structure Refinement from ESI.
