Materials Data on Ba2EuMoO6 by Materials Project

Abstract

Ba2EuMoO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Ba2+ is bonded to twelve equivalent O2- atoms to form BaO12 cuboctahedra that share corners with twelve equivalent BaO12 cuboctahedra, faces with six equivalent BaO12 cuboctahedra, faces with four equivalent EuO6 octahedra, and faces with four equivalent MoO6 octahedra. All Ba–O bond lengths are 3.06 Å. Eu2+ is bonded to six equivalent O2- atoms to form EuO6 octahedra that share corners with six equivalent MoO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Eu–O bond lengths are 2.35 Å. Mo6+ is bonded to six equivalent O2- atoms to form MoO6 octahedra that share corners with six equivalent EuO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Mo–O bond lengths are 1.97 Å. O2- is bonded in a distorted linear geometry to four equivalent Ba2+, one Eu2+, and one Mo6+ atom.
