Title: Materials Data on Mg6VBiO8 by Materials Project

Abstract

Mg6VBiO8 is alpha Po-derived structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. there are three inequivalent Mg2+ sites. In the first Mg2+ site, Mg2+ is bonded to six O2- atoms to form MgO6 octahedra that share corners with six MgO6 octahedra, edges with four equivalent VO6 octahedra, and edges with eight equivalent MgO6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Mg–O bond lengths are 2.25 Å. In the second Mg2+ site, Mg2+ is bonded to six O2- atoms to form MgO6 octahedra that share corners with six MgO6 octahedra, edges with four equivalent BiO6 octahedra, and edges with eight equivalent MgO6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are four shorter (2.25 Å) and two longer (2.27 Å) Mg–O bond lengths. In the third Mg2+ site, Mg2+ is bonded to six O2- atoms to form MgO6 octahedra that share corners with six equivalent MgO6 octahedra, edges with two equivalent VO6 octahedra, edges with two equivalent BiO6 octahedra, and edges with eight MgO6 octahedra. The corner-sharing octahedra tilt angles range from 0–7°. There are a spread of Mg–O bond distances ranging from 2.12–2.41 Å. V3+ is bonded to six O2- atoms tomore » form VO6 octahedra that share corners with two equivalent BiO6 octahedra, corners with four equivalent VO6 octahedra, and edges with twelve MgO6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are two shorter (2.10 Å) and four longer (2.25 Å) V–O bond lengths. Bi1+ is bonded to six O2- atoms to form BiO6 octahedra that share corners with two equivalent VO6 octahedra, corners with four equivalent BiO6 octahedra, and edges with twelve MgO6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are four shorter (2.25 Å) and two longer (2.43 Å) Bi–O bond lengths. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded to four equivalent Mg2+, one V3+, and one Bi1+ atom to form OMg4VBi octahedra that share corners with six equivalent OMg4VBi octahedra and edges with twelve OMg6 octahedra. The corner-sharing octahedra tilt angles range from 0–1°. In the second O2- site, O2- is bonded to six Mg2+ atoms to form OMg6 octahedra that share corners with six equivalent OMg6 octahedra and edges with twelve OMg4VBi octahedra. The corner-sharing octahedra tilt angles range from 0–7°. In the third O2- site, O2- is bonded to four Mg2+ and two equivalent V3+ atoms to form OMg4V2 octahedra that share corners with six OMg4V2 octahedra and edges with twelve OMg4VBi octahedra. The corner-sharing octahedral tilt angles are 0°. In the fourth O2- site, O2- is bonded to four Mg2+ and two equivalent Bi1+ atoms to form OMg4Bi2 octahedra that share corners with six OMg4V2 octahedra and edges with twelve OMg4VBi octahedra. The corner-sharing octahedral tilt angles are 0°. In the fifth O2- site, O2- is bonded to four Mg2+ and two equivalent V3+ atoms to form OMg4V2 octahedra that share corners with six OMg4V2 octahedra and edges with twelve OMg4VBi octahedra. The corner-sharing octahedral tilt angles are 0°. Both O–Mg bond lengths are 2.12 Å. In the sixth O2- site, O2- is bonded to four Mg2+ and two equivalent Bi1+ atoms to form OMg4Bi2 octahedra that share corners with six OMg4V2 octahedra and edges with twelve OMg4VBi octahedra. The corner-sharing octahedral tilt angles are 0°. Both O–Mg bond lengths are 2.41 Å.« less
