Title: Materials Data on Sn2Sb2Pb4O13 by Materials Project

Abstract

Pb4Sn2Sb2O13 crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional. there are two inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded to seven O2- atoms to form distorted PbO7 hexagonal pyramids that share corners with three PbO7 hexagonal pyramids, edges with three PbO7 hexagonal pyramids, edges with two equivalent SnO6 octahedra, and edges with four equivalent SbO6 octahedra. There are a spread of Pb–O bond distances ranging from 2.32–2.72 Å. In the second Pb2+ site, Pb2+ is bonded to seven O2- atoms to form distorted PbO7 hexagonal pyramids that share corners with three PbO7 hexagonal pyramids, edges with three PbO7 hexagonal pyramids, edges with two equivalent SbO6 octahedra, and edges with four equivalent SnO6 octahedra. There are a spread of Pb–O bond distances ranging from 2.35–2.69 Å. Sn4+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with two equivalent SnO6 octahedra, corners with four equivalent SbO6 octahedra, and edges with six PbO7 hexagonal pyramids. The corner-sharing octahedra tilt angles range from 45–49°. There are a spread of Sn–O bond distances ranging from 2.07–2.11 Å. Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with twomore » equivalent SbO6 octahedra, corners with four equivalent SnO6 octahedra, and edges with six PbO7 hexagonal pyramids. The corner-sharing octahedra tilt angles range from 42–46°. There are a spread of Sb–O bond distances ranging from 2.00–2.04 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Pb2+ and two equivalent Sn4+ atoms. In the second O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Pb2+ and two equivalent Sb5+ atoms. In the third O2- site, O2- is bonded in a 2-coordinate geometry to two Pb2+, one Sn4+, and one Sb5+ atom. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Pb2+ and two equivalent Sn4+ atoms. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Pb2+ and two equivalent Sb5+ atoms. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to two Pb2+, one Sn4+, and one Sb5+ atom. In the seventh O2- site, O2- is bonded in a tetrahedral geometry to four Pb2+ atoms.« less
