Materials Data on Ge(TeO3)2 by Materials Project

Abstract

Ge(TeO3)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Ge4+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Ge–O bond distances ranging from 1.91–1.93 Å. Te4+ is bonded in a 3-coordinate geometry to three O2- atoms. There are a spread of Te–O bond distances ranging from 1.91–1.93 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one Ge4+ and one Te4+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Ge4+ and one Te4+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Ge4+ and one Te4+ atom.
