Materials Data on MgGeO3 by Materials Project
Abstract
MgGeO3 is Ilmenite structured and crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Mg2+ is bonded to six equivalent O2- atoms to form distorted MgO6 octahedra that share corners with nine equivalent GeO6 octahedra, edges with three equivalent MgO6 octahedra, and a faceface with one GeO6 octahedra. The corner-sharing octahedra tilt angles range from 42–61°. There are three shorter (2.04 Å) and three longer (2.21 Å) Mg–O bond lengths. Ge4+ is bonded to six equivalent O2- atoms to form GeO6 octahedra that share corners with nine equivalent MgO6 octahedra, edges with three equivalent GeO6 octahedra, and a faceface with one MgO6 octahedra. The corner-sharing octahedra tilt angles range from 42–61°. There is three shorter (1.89 Å) and three longer (1.98 Å) Ge–O bond length. O2- is bonded in a distorted see-saw-like geometry to two equivalent Mg2+ and two equivalent Ge4+ atoms.
