Materials Data on AgGeO3 by Materials Project

Abstract

AgGeO3 crystallizes in the orthorhombic Pmma space group. The structure is three-dimensional. Ag2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Ag–O bond distances ranging from 2.17–2.53 Å. Ge4+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing GeO6 octahedra. The corner-sharing octahedral tilt angles are 32°. There is two shorter (1.86 Å) and four longer (1.98 Å) Ge–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Ag2+ and two equivalent Ge4+ atoms to form a mixture of distorted edge and corner-sharing OAg2Ge2 tetrahedra. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Ag2+ and two equivalent Ge4+ atoms.
