Materials Data on SrAgO2 by Materials Project
SrAgO2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Sr2+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing SrO6 octahedra. The corner-sharing octahedra tilt angles range from 13–35°. There are a spread of Sr–O bond distances ranging from 2.53–2.61 Å. 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 (2.12 Å) and two longer (2.71 Å) Ag–O bond lengths. In the second Ag2+ site, Ag2+ is bonded in a square co-planar geometry to four O2- atoms. There are two shorter (2.10 Å) and two longer (2.11 Å) Ag–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to four equivalent Sr2+ and two Ag2+ atoms to form a mixture of distorted corner and edge-sharing OSr4Ag2 octahedra. The corner-sharing octahedral tilt angles are 0°. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Sr2+ and two Ag2+ atoms.
