Title: Materials Data on GeO2 by Materials Project

Abstract

GeO2 is quartz (alpha)-like structured and crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Ge4+ sites. In the first Ge4+ site, Ge4+ is bonded to four O2- atoms to form corner-sharing GeO4 tetrahedra. There are a spread of Ge–O bond distances ranging from 1.73–1.77 Å. In the second Ge4+ site, Ge4+ is bonded to four O2- atoms to form corner-sharing GeO4 tetrahedra. There is one shorter (1.75 Å) and three longer (1.76 Å) Ge–O bond length. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a linear geometry to two equivalent Ge4+ atoms. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Ge4+ atoms. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to two Ge4+ atoms. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to two Ge4+ atoms. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to two Ge4+ atoms.
