Materials Data on Eu2MgWO6 by Materials Project

Abstract

MgEu2WO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Mg2+ is bonded to six equivalent O2- atoms to form MgO6 octahedra that share corners with six equivalent WO6 octahedra and faces with eight equivalent EuO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Mg–O bond lengths are 2.05 Å. Eu2+ is bonded to twelve equivalent O2- atoms to form EuO12 cuboctahedra that share corners with twelve equivalent EuO12 cuboctahedra, faces with six equivalent EuO12 cuboctahedra, faces with four equivalent MgO6 octahedra, and faces with four equivalent WO6 octahedra. All Eu–O bond lengths are 2.83 Å. W6+ is bonded to six equivalent O2- atoms to form WO6 octahedra that share corners with six equivalent MgO6 octahedra and faces with eight equivalent EuO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All W–O bond lengths are 1.96 Å. O2- is bonded in a distorted linear geometry to one Mg2+, four equivalent Eu2+, and one W6+ atom.
