Starting materials: HI, H3PO2, SnI2, (CH3)2CHNH3I
Product: yellow crystals
Description: Aq HI (7.58M, 6.8mL) and aq H3PO2 (9.14M, 1.7mL) mixture in a flask was degassed by nitrogen. SnI2 (2mmol) was then dissolved into the mixture and the flask was brought to boiling at 130°C using an oil bath under constant stirring. Solid (CH3)2CHNH3I (4mmol) was added to the solution, forming a yellow precipitate. Solution was raised to 200°C, were the precipitate changed from yellow to red. Solution was left to cool, leading to the yellow color.
Method: Single crystal X-ray diffraction
Description: SC-XRD was performed with a STOE IPDS II or IPDS 2T diffractometer with Mo Kα radiation (λ = 0.71073 Å), operating at 50 kV and 40 mA. Integration/numerical absorption corrections were executed with X-AREA, X-RED, and X-SHAPE programs.
