Materials Data on Ba4NbCo2MoO12 by Materials Project
Abstract
Ba4NbMoCo2O12 is (Cubic) Perovskite-derived structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with twelve equivalent BaO12 cuboctahedra, faces with six equivalent BaO12 cuboctahedra, faces with two equivalent NbO6 octahedra, faces with two equivalent MoO6 octahedra, and faces with four CoO6 octahedra. There are a spread of Ba–O bond distances ranging from 2.88–2.91 Å. Nb5+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with six CoO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. There are four shorter (2.00 Å) and two longer (2.10 Å) Nb–O bond lengths. Mo6+ is bonded to six O2- atoms to form MoO6 octahedra that share corners with six CoO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. There is two shorter (1.92 Å) and four longer (1.98 Å) Mo–O bond length. There are two inequivalent Co+2.50+ sites. In the first Co+2.50+ site, Co+2.50+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with two equivalent NbO6 octahedra, corners with four equivalent MoO6 octahedra,more »
