Materials Data on GePb3O5 by Materials Project
Pb3GeO5 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are three inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Pb–O bond distances ranging from 2.24–2.61 Å. In the second Pb2+ site, Pb2+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are a spread of Pb–O bond distances ranging from 2.26–2.62 Å. In the third Pb2+ site, Pb2+ is bonded in a 4-coordinate geometry to five O2- atoms. There are a spread of Pb–O bond distances ranging from 2.33–3.05 Å. Ge4+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Ge–O bond distances ranging from 1.77–1.80 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two Pb2+ and one Ge4+ atom. In the second O2- site, O2- is bonded in a trigonal non-coplanar geometry to three Pb2+ atoms. In the third O2- site, O2- is bonded in a 1-coordinate geometry to three Pb2+ and one Ge4+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to two Pb2+ and one Ge4+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to three Pb2+ and one Ge4+ atom.
