Title: Materials Data on Ge3Pb5O11 by Materials Project

Abstract

Pb5Ge3O11 crystallizes in the hexagonal P-6 space group. The structure is three-dimensional. there are six inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded to six O2- atoms to form distorted PbO6 pentagonal pyramids that share corners with four GeO4 tetrahedra and an edgeedge with one GeO4 tetrahedra. There are a spread of Pb–O bond distances ranging from 2.22–2.78 Å. In the second Pb2+ site, Pb2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Pb–O bond distances ranging from 2.47–3.12 Å. In the third 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 2.24–2.89 Å. In the fourth Pb2+ site, Pb2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are three shorter (2.48 Å) and three longer (2.80 Å) Pb–O bond lengths. In the fifth Pb2+ site, Pb2+ is bonded to six equivalent O2- atoms to form distorted PbO6 pentagonal pyramids that share corners with six equivalent GeO4 tetrahedra. All Pb–O bond lengths are 2.50 Å. In the sixth Pb2+ site, Pb2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There aremore » six shorter (2.69 Å) and three longer (3.03 Å) Pb–O bond lengths. There are two inequivalent Ge4+ sites. In the first Ge4+ site, Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with two PbO6 pentagonal pyramids and a cornercorner with one GeO4 tetrahedra. There are a spread of Ge–O bond distances ranging from 1.75–1.84 Å. In the second Ge4+ site, Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with two equivalent PbO6 pentagonal pyramids and an edgeedge with one PbO6 pentagonal pyramid. All Ge–O bond lengths are 1.78 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one Pb2+ and two equivalent Ge4+ atoms. In the second O2- site, O2- is bonded in a 2-coordinate geometry to three Pb2+ and one Ge4+ atom. 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 distorted single-bond geometry to three Pb2+ and one Ge4+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to two Pb2+ and one Ge4+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to three Pb2+ and one Ge4+ atom. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to three Pb2+ and one Ge4+ atom.« less
