Herein we present the crystal structure of lithium hexafluoridoplumbate(IV) determined from powder X‐ray diffraction data. The cell parameters are a = 5.01067(3), c = 4.66340(5) Å, V = 101.3969(13) Å 3 at T = 293 K. Li 2 PbF 6 is isotypic to Li 2 ZrF 6 , space group P 3 1 m (no. 162). The measured Raman spectrum is compared with the quantum chemically calculated spectrum. Furthermore, we determined the decomposition temperature of Li 2 PbF 6 . We also present the corrected space group and crystal structure for SrPbF 6 which was previously reported as P 4 2 / mmc (no. 131) and could now be corrected to space group P 4 2 / mcm [no. 132, a = 5.21719(3), c = 8.92771(11) Å, V = 243.004(4) Å 3 , T = 293 K].
