Materials Data on BaMgV2ZnO8 by Materials Project
Abstract
BaMgV2ZnO8 crystallizes in the orthorhombic Iba2 space group. The structure is three-dimensional. Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with two equivalent MgO6 octahedra, corners with two equivalent ZnO6 octahedra, corners with four VO4 tetrahedra, edges with four VO4 tetrahedra, faces with two equivalent BaO12 cuboctahedra, faces with two equivalent MgO6 octahedra, and faces with two equivalent ZnO6 octahedra. The corner-sharing octahedral tilt angles are 51°. There are a spread of Ba–O bond distances ranging from 2.79–3.15 Å. Mg2+ is bonded to six O2- atoms to form MgO6 octahedra that share corners with two equivalent BaO12 cuboctahedra, corners with six VO4 tetrahedra, an edgeedge with one MgO6 octahedra, an edgeedge with one ZnO6 octahedra, and faces with two equivalent BaO12 cuboctahedra. There are a spread of Mg–O bond distances ranging from 2.07–2.20 Å. There are three inequivalent V5+ sites. In the first V5+ site, V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share corners with two equivalent BaO12 cuboctahedra, corners with two equivalent MgO6 octahedra, corners with four equivalent ZnO6 octahedra, and edges with two equivalent BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 45–56°. There is twomore »
