Title: Materials Data on Zn2GeO4 by Materials Project

Abstract

Zn2GeO4 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. there are two inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share corners with four ZnO4 tetrahedra and corners with four equivalent GeO4 tetrahedra. There are a spread of Zn–O bond distances ranging from 1.97–1.99 Å. In the second Zn2+ site, Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share corners with four ZnO4 tetrahedra and corners with four equivalent GeO4 tetrahedra. There are a spread of Zn–O bond distances ranging from 1.97–2.01 Å. Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with eight ZnO4 tetrahedra. There is one shorter (1.77 Å) and three longer (1.78 Å) Ge–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Zn2+ and one Ge4+ atom. In the second O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Zn2+ and one Ge4+ atom. In the third O2- site, O2- is bonded in a trigonal planar geometry to two Zn2+ and onemore » Ge4+ atom. In the fourth O2- site, O2- is bonded in a trigonal planar geometry to two Zn2+ and one Ge4+ atom.« less
