Materials Data on VPPb3O8 by Materials Project
VPb3PO8 crystallizes in the trigonal R3m space group. The structure is three-dimensional. V5+ is bonded in a tetrahedral geometry to four O2- atoms. There is one shorter (1.73 Å) and three longer (1.74 Å) V–O bond length. There are three inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded in a distorted single-bond geometry to ten O2- atoms. There are a spread of Pb–O bond distances ranging from 2.33–3.07 Å. In the second Pb2+ site, Pb2+ is bonded in a 1-coordinate geometry to ten O2- atoms. There are a spread of Pb–O bond distances ranging from 2.33–2.92 Å. In the third Pb2+ site, Pb2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are three shorter (2.58 Å) and three longer (2.68 Å) Pb–O bond lengths. P5+ is bonded in a tetrahedral geometry to four O2- atoms. All P–O bond lengths are 1.56 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to one Pb2+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted linear geometry to one V5+ and one Pb2+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to four Pb2+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one V5+ and four Pb2+ atoms.
