Materials Data on Cr2P4Pb3O16 by Materials Project
Abstract
Cr2Pb3(PO4)4 crystallizes in the tetragonal P4_12_12 space group. The structure is three-dimensional. Cr3+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with six PO4 tetrahedra. There are a spread of Cr–O bond distances ranging from 1.99–2.04 Å. There are two inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded in a 7-coordinate geometry to four O2- atoms. There are a spread of Pb–O bond distances ranging from 2.42–2.50 Å. In the second Pb2+ site, Pb2+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Pb–O bond distances ranging from 2.57–2.76 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 three equivalent CrO6 octahedra. The corner-sharing octahedra tilt angles range from 34–46°. There are a spread of P–O bond distances ranging from 1.53–1.56 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent CrO6 octahedra. The corner-sharing octahedra tilt angles range from 40–46°. There are a spread of P–O bond distances ranging from 1.54–1.57 Å. Theremore »
