Transparent and light brownish single crystals of Pb 5 GeO 7 were grown from a melt of composition 4.8PbO.GeO 2 by spontaneous crystallization. The compound melts incongruently at 1014 K. The unit cell is orthorhombic with lattice constants a = 9.296 (2), b = 11.546 (2), c = 17.298 (5) Å; D m (293 K) = 8.63 (4), D x = 8.734 Mg m −3 for Z = 8. The space group is Pbca . Indexed X‐ray powder data are given.
