Materials Data on AgGeO3 by Materials Project

Abstract

AgGeO3 crystallizes in the triclinic P1 space group. The structure is two-dimensional and consists of two AgGeO3 sheets oriented in the (0, 0, 1) direction. there are two inequivalent Ag2+ sites. In the first Ag2+ site, Ag2+ is bonded in a distorted square co-planar geometry to four O2- atoms. There are two shorter (2.13 Å) and two longer (2.14 Å) Ag–O bond lengths. In the second Ag2+ site, Ag2+ is bonded in a distorted square co-planar geometry to four O2- atoms. There are two shorter (2.12 Å) and two longer (2.13 Å) Ag–O bond lengths. 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 is two shorter (1.78 Å) and two longer (1.84 Å) Ge–O bond length. In the second Ge4+ site, Ge4+ is bonded to four O2- atoms to form corner-sharing GeO4 tetrahedra. There is two shorter (1.78 Å) and two longer (1.84 Å) Ge–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Ag2+ and one Ge4+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Ag2+ and one Ge4+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent Ge4+ atoms. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent Ge4+ atoms. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Ag2+ and one Ge4+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Ag2+ and one Ge4+ atom.
