Materials Data on Zn3Sn2(GeO4)3 by Materials Project

Zn3Sn2(GeO4)3 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 (2.35 Å) and four longer (2.52 Å) Zn–O bond lengths. Sn3+ is bonded to six equivalent O2- atoms to form SnO6 octahedra that share corners with six equivalent GeO4 tetrahedra. All Sn–O bond lengths are 2.13 Å. Ge4+ is bonded to four equivalent O2- atoms to form GeO4 tetrahedra that share corners with four equivalent SnO6 octahedra. The corner-sharing octahedral tilt angles are 54°. All Ge–O bond lengths are 1.82 Å. O2- is bonded in a 4-coordinate geometry to two equivalent Zn2+, one Sn3+, and one Ge4+ atom.
