Materials Data on Pb5SO8 by Materials Project
Pb5SO8 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are five inequivalent Pb+3.60+ sites. In the first Pb+3.60+ site, Pb+3.60+ is bonded in a 3-coordinate geometry to three O2- atoms. There are a spread of Pb–O bond distances ranging from 2.27–2.34 Å. In the second Pb+3.60+ site, Pb+3.60+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Pb–O bond distances ranging from 2.37–2.48 Å. In the third Pb+3.60+ site, Pb+3.60+ is bonded in a 6-coordinate geometry to three O2- atoms. There are two shorter (2.31 Å) and one longer (2.33 Å) Pb–O bond lengths. In the fourth Pb+3.60+ site, Pb+3.60+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Pb–O bond distances ranging from 2.29–3.03 Å. In the fifth Pb+3.60+ site, Pb+3.60+ is bonded in a 3-coordinate geometry to three O2- atoms. There are a spread of Pb–O bond distances ranging from 2.23–2.49 Å. S2- is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.49–1.51 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded to four Pb+3.60+ atoms to form a mixture of distorted edge and corner-sharing OPb4 tetrahedra. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to three Pb+3.60+ atoms. In the third O2- site, O2- is bonded in a single-bond geometry to one Pb+3.60+ and one S2- atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one Pb+3.60+ and one S2- atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one Pb+3.60+ and one S2- atom. In the sixth O2- site, O2- is bonded in a single-bond geometry to one S2- atom. In the seventh O2- site, O2- is bonded to four Pb+3.60+ atoms to form a mixture of edge and corner-sharing OPb4 tetrahedra. In the eighth O2- site, O2- is bonded to four Pb+3.60+ atoms to form a mixture of edge and corner-sharing OPb4 tetrahedra.
