Materials Data on ScNb(PbO3)2 by Materials Project
ScNb(PbO3)2 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Sc3+ is bonded to six equivalent O2- atoms to form ScO6 octahedra that share corners with six equivalent NbO6 octahedra and faces with eight equivalent PbO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Sc–O bond lengths are 2.10 Å. Nb5+ is bonded to six equivalent O2- atoms to form NbO6 octahedra that share corners with six equivalent ScO6 octahedra and faces with eight equivalent PbO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Nb–O bond lengths are 2.01 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 ScO6 octahedra, and faces with four equivalent NbO6 octahedra. All Pb–O bond lengths are 2.91 Å. O2- is bonded in a linear geometry to one Sc3+, one Nb5+, and four equivalent Pb2+ atoms.
