Materials Data on MnTe(PbO3)2 by Materials Project

Abstract

MnTe(PbO3)2 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Mn2+ is bonded to six equivalent O2- atoms to form MnO6 octahedra that share corners with six equivalent TeO6 octahedra and faces with eight equivalent PbO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Mn–O bond lengths are 2.14 Å. Pb2+ is bonded to twelve equivalent O2- atoms to form PbO12 cuboctahedra that share corners with twelve equivalent PbO12 cuboctahedra, faces with six equivalent PbO12 cuboctahedra, faces with four equivalent MnO6 octahedra, and faces with four equivalent TeO6 octahedra. All Pb–O bond lengths are 2.90 Å. Te6+ is bonded to six equivalent O2- atoms to form TeO6 octahedra that share corners with six equivalent MnO6 octahedra and faces with eight equivalent PbO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Te–O bond lengths are 1.95 Å. O2- is bonded in a linear geometry to one Mn2+, four equivalent Pb2+, and one Te6+ atom.
