Materials Data on Mg3Ge3(SbO6)2 by Materials Project

Abstract

Mg3Ge3(SbO6)2 crystallizes in the cubic Ia-3d space group. The structure is three-dimensional. Mg2+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. There are four shorter (2.37 Å) and four longer (2.46 Å) Mg–O bond lengths. Ge4+ is bonded to four equivalent O2- atoms to form GeO4 tetrahedra that share corners with four equivalent SbO6 octahedra. The corner-sharing octahedral tilt angles are 59°. All Ge–O bond lengths are 1.79 Å. Sb3+ is bonded to six equivalent O2- atoms to form SbO6 octahedra that share corners with six equivalent GeO4 tetrahedra. All Sb–O bond lengths are 2.25 Å. O2- is bonded in a 4-coordinate geometry to two equivalent Mg2+, one Ge4+, and one Sb3+ atom.
