Materials Data on FePb2WO6 by Materials Project

Abstract

WFePb2O6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. W6+ is bonded to six equivalent O2- atoms to form WO6 octahedra that share corners with six equivalent FeO6 octahedra and faces with eight equivalent PbO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All W–O bond lengths are 1.96 Å. Fe2+ is bonded to six equivalent O2- atoms to form FeO6 octahedra that share corners with six equivalent WO6 octahedra and faces with eight equivalent PbO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Fe–O bond lengths are 2.05 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 WO6 octahedra, and faces with four equivalent FeO6 octahedra. All Pb–O bond lengths are 2.84 Å. O2- is bonded in a distorted linear geometry to one W6+, one Fe2+, and four equivalent Pb2+ atoms.
