Data collection: Siemens Bruker CCD diffractometer, 3537 total reflections, 810 unique reflections, 569 unique reflections, Fo| ≥ 4σFo. The structure was solved by direct methods and refined to R1, 0.0402, wR2, 0.067, and S, 0.983. Quantitative electron microprobe analysis provided the chemical formula Pb5.99-La1.03O7Br 0.91.

    • 13 Electron microprobe analysis allowed the determination of Pb, La, and Cl. However, we were unable to get the correct chemical composition because of the overlapping of the Mα line for Pb and the Kα line for Cl.
