Materials Data on Ag(OsO3)2 by Materials Project
Ag(OsO3)2 crystallizes in the orthorhombic Ima2 space group. The structure is three-dimensional. there are two inequivalent Os+5.50+ sites. In the first Os+5.50+ site, Os+5.50+ is bonded to six O2- atoms to form corner-sharing OsO6 octahedra. The corner-sharing octahedra tilt angles range from 35–46°. There are a spread of Os–O bond distances ranging from 1.87–1.96 Å. In the second Os+5.50+ site, Os+5.50+ is bonded to six O2- atoms to form corner-sharing OsO6 octahedra. The corner-sharing octahedra tilt angles range from 35–46°. There are a spread of Os–O bond distances ranging from 1.89–1.97 Å. Ag1+ is bonded in a hexagonal planar geometry to six O2- atoms. There are a spread of Ag–O bond distances ranging from 2.50–2.79 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Os+5.50+ and two equivalent Ag1+ atoms. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Os+5.50+ atoms. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two Os+5.50+ and one Ag1+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to two Os+5.50+ and one Ag1+ atom.
