Synthesis and characterization of PbBaGeO4

Abstract

PbBaGeO4 was prepared by high-temperature solid-state synthesis at 900°C in a platinum crucible from lead(II) oxide, barium carbonate, and germanium(IV) oxide. This compound crystallizes with the BaNdGaO4 structure type in the orthorhombic space group P212121 (no. 19). The structure was refined from single-crystal X-ray diffraction data: a = 1021.6(2), b = 763.4(2), c = 618.1(2) pm, V = 482.1(2) Å3, and residuals of R1 = 0.0373 and wR2 = 0.0730 for all data. Next to structural data, Raman spectroscopic data of PbBaGeO4 are reported.
