Materials Data on GePbO3 by Materials Project
PbGeO3 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Pb2+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Pb–O bond distances ranging from 2.30–2.60 Å. Ge4+ is bonded to four O2- atoms to form corner-sharing GeO4 tetrahedra. There are a spread of Ge–O bond distances ranging from 1.76–1.80 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent Ge4+ atoms. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Pb2+ and one Ge4+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Pb2+ and one Ge4+ atom.
