Materials Data on Ba2ZnReO6 by Materials Project

Abstract

Ba2ReZnO6 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 ReO6 octahedra, and faces with four equivalent ZnO6 octahedra. All Ba–O bond lengths are 2.91 Å. Re6+ is bonded to six equivalent O2- atoms to form ReO6 octahedra that share corners with six equivalent ZnO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Re–O bond lengths are 1.95 Å. Zn2+ is bonded to six equivalent O2- atoms to form ZnO6 octahedra that share corners with six equivalent ReO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Zn–O bond lengths are 2.16 Å. O2- is bonded in a distorted linear geometry to four equivalent Ba2+, one Re6+, and one Zn2+ atom.
