Starting materials: pyridine, iodoethylammonium iodide, anhydrous acetonitrile, PbI2, HI
Product: red plate crystals
Description: First, PyrEAI was synthesized by charging a flamed-dried two-neck round bottom flask with pyridine (1.05 equivalent), iodoethylammonium iodide (1.00 equivalent), and anhydrous acetonitrile (which was dried with CaH2 before distillation). The mixture was heated and stirred at reflux for 2 days. The mixture was then cooled to room temperature. The precipitate was isolated by filtration, washed with diethyl ether, and dried. Then, stoichiometric amounts of PbI2 (purchased from Sigma Aldrich) and PyrEAI were added to concentrated stabilized aqueous HI. The concentration of the solution was maintained at 0.25-0.30M of Pb2+. The solution was heated at 140ºC and stirred for an hour. The resulting clear solution was cooled slowly to room temperature.
Method: Single Crystal X-ray Diffraction
Description: Data was collected with a BrukerX8 CCD area detector diffractometer, with Mo Kα radiation (0.71073Å) at 100 K. SAINT and SADABS packages were used for data reduction and absorption corrections, respectively.
