Materials Data on Ba2NdNbO6 by Materials Project
Ba2NdNbO6 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 NdO6 octahedra, and faces with four equivalent NbO6 octahedra. All Ba–O bond lengths are 3.09 Å. Nd3+ is bonded to six equivalent O2- atoms to form NdO6 octahedra that share corners with six equivalent NbO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Nd–O bond lengths are 2.33 Å. Nb5+ is bonded to six equivalent O2- atoms to form NbO6 octahedra that share corners with six equivalent NdO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Nb–O bond lengths are 2.02 Å. O2- is bonded in a distorted linear geometry to four equivalent Ba2+, one Nd3+, and one Nb5+ atom.
