Materials Data on SrAgO2 by Materials Project
SrAgO2 is Corundum-derived structured and crystallizes in the orthorhombic Pmma 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 0–44°. There are a spread of Sr–O bond distances ranging from 2.47–2.66 Å. Ag2+ is bonded in a square co-planar geometry to four O2- atoms. There are two shorter (2.12 Å) and two longer (2.29 Å) Ag–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Sr2+ and two equivalent Ag2+ atoms to form distorted OSr2Ag2 trigonal pyramids that share corners with four equivalent OSr4Ag2 octahedra, corners with four equivalent OSr2Ag2 trigonal pyramids, and edges with four equivalent OSr4Ag2 octahedra. The corner-sharing octahedral tilt angles are 75°. In the second O2- site, O2- is bonded to four equivalent Sr2+ and two equivalent Ag2+ atoms to form OSr4Ag2 octahedra that share corners with six equivalent OSr4Ag2 octahedra, corners with four equivalent OSr2Ag2 trigonal pyramids, edges with four equivalent OSr4Ag2 octahedra, and edges with four equivalent OSr2Ag2 trigonal pyramids. The corner-sharing octahedra tilt angles range from 0–1°.
