Materials Data on P2Pb3O8 by Materials Project
Pb3(PO4)2 crystallizes in the trigonal P3 space group. The structure is three-dimensional. there are five 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 equivalent PbO6 pentagonal pyramids, corners with four PO4 tetrahedra, and an edgeedge with one PO4 tetrahedra. There are a spread of Pb–O bond distances ranging from 2.30–2.73 Å. In the second Pb2+ site, Pb2+ is bonded to six O2- atoms to form distorted PbO6 pentagonal pyramids that share corners with four equivalent PbO6 pentagonal pyramids, corners with four PO4 tetrahedra, and an edgeedge with one PO4 tetrahedra. There are a spread of Pb–O bond distances ranging from 2.26–2.84 Å. In the third 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 2.50–2.98 Å. In the fourth 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 2.54–2.95 Å. In the fifth 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 2.55–2.92 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four PbO6 pentagonal pyramids and an edgeedge with one PbO6 pentagonal pyramid. There are a spread of P–O bond distances ranging from 1.54–1.58 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four PbO6 pentagonal pyramids and an edgeedge with one PbO6 pentagonal pyramid. There is two shorter (1.55 Å) and two longer (1.57 Å) P–O bond length. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three Pb2+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three Pb2+ and one P5+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to three Pb2+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to two Pb2+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to two Pb2+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to three Pb2+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to three Pb2+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to two Pb2+ and one P5+ atom.
