Materials Data on AgPtO2 by Materials Project
PtAgO2 crystallizes in the monoclinic P2/m space group. The structure is three-dimensional. there are two inequivalent Pt2+ sites. In the first Pt2+ site, Pt2+ is bonded to six O2- atoms to form edge-sharing PtO6 octahedra. There are four shorter (2.05 Å) and two longer (2.06 Å) Pt–O bond lengths. In the second Pt2+ site, Pt2+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Pt–O bond lengths are 2.05 Å. There are two inequivalent Ag2+ sites. In the first Ag2+ site, Ag2+ is bonded in a linear geometry to two equivalent O2- atoms. Both Ag–O bond lengths are 2.18 Å. In the second Ag2+ site, Ag2+ is bonded in a distorted linear geometry to six O2- atoms. There are two shorter (2.21 Å) and four longer (2.86 Å) Ag–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Pt2+ and two Ag2+ atoms to form a mixture of edge and corner-sharing OAg2Pt2 tetrahedra. In the second O2- site, O2- is bonded in a 3-coordinate geometry to three Pt2+ and two equivalent Ag2+ atoms.
