Materials Data on InSb3Pb4O13 by Materials Project
InPb4Sb3O13 crystallizes in the trigonal R3m space group. The structure is three-dimensional. In3+ is bonded to six O2- atoms to form InO6 octahedra that share corners with six equivalent SbO6 octahedra and edges with six equivalent PbO7 hexagonal pyramids. The corner-sharing octahedra tilt angles range from 49–50°. There are three shorter (2.18 Å) and three longer (2.20 Å) In–O bond lengths. 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 equivalent PbO7 hexagonal pyramids, edges with three equivalent PbO7 hexagonal pyramids, and edges with six equivalent SbO6 octahedra. There are one shorter (2.29 Å) and six longer (2.69 Å) Pb–O bond lengths. 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 InO6 octahedra, and edges with four equivalent SbO6 octahedra. There are a spread of Pb–O bond distances ranging from 2.35–2.78 Å. Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with two equivalent InO6 octahedra, corners with four equivalent SbO6 octahedra, and edges with six PbO7 hexagonal pyramids. The corner-sharing octahedra tilt angles range from 42–50°. There are a spread of Sb–O bond distances ranging from 1.97–2.05 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a tetrahedral geometry to four Pb2+ atoms. In the second O2- site, O2- is bonded in a 4-coordinate geometry to one In3+, two equivalent Pb2+, and one Sb5+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to two Pb2+ and two equivalent Sb5+ atoms. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to one In3+, two equivalent Pb2+, and one Sb5+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to two Pb2+ and two equivalent Sb5+ atoms.
