Starting materials: PbBr2, HBr, C7H13NH2
Product: Colorless crystals
Description: PbBr2 was dissolved in an HBr solution. Then, the cyclic amine was added and immediately resulted in the precipitation of a solid, which was re-dissolved by refluxing for 1-12 hours. The solution was then cooled slowly to room temperature, causing crystals to precipitate.
Method: Single-crystal X-ray diffraction
Description: A Bruker SMART 1K CCD area detector diffractometer using Mo Kalpha radiation was used to collect the SCXRD data. Omega-scans of width 0.3 degrees were used. The SAINT+ program, version 6.02, was used to perform data reduction and the XPREP program was used to perform face indexed absorption corrections. The SHELXS-97 program was used for solving the structure, and the SHELXL-97 program was used to refine it by full matrix least-squares minimization.
