Materials Data on Zn3Ge3(SbO6)2 by Materials Project

Abstract

Zn3Ge3(SbO6)2 crystallizes in the cubic Ia-3d space group. The structure is three-dimensional. Zn2+ is bonded in a distorted body-centered cubic geometry to eight equivalent O2- atoms. There are four shorter (2.36 Å) and four longer (2.49 Å) Zn–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 58°. All Ge–O bond lengths are 1.80 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 2.24 Å. O2- is bonded in a 4-coordinate geometry to two equivalent Zn2+, one Ge4+, and one Sb3+ atom.
