Materials Data on Ag2GeO3 by Materials Project

Abstract

Ag2GeO3 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. there are two inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a distorted see-saw-like geometry to four O2- atoms. There are a spread of Ag–O bond distances ranging from 2.18–2.68 Å. In the second Ag1+ site, Ag1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Ag–O bond distances ranging from 2.32–2.76 Å. Ge4+ is bonded to four O2- atoms to form corner-sharing GeO4 tetrahedra. There are a spread of Ge–O bond distances ranging from 1.75–1.81 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to three Ag1+ and one Ge4+ atom to form a mixture of edge and corner-sharing OAg3Ge tetrahedra. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two Ag1+ and two equivalent Ge4+ atoms. In the third O2- site, O2- is bonded to three Ag1+ and one Ge4+ atom to form a mixture of distorted edge and corner-sharing OAg3Ge trigonal pyramids.
