Materials Data on Ag2SnO3 by Materials Project
Ag2SnO3 crystallizes in the hexagonal P6_322 space group. The structure is three-dimensional. there are two inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a linear geometry to two equivalent O2- atoms. Both Ag–O bond lengths are 2.11 Å. In the second Ag1+ site, Ag1+ is bonded to six equivalent O2- atoms to form distorted AgO6 octahedra that share edges with six SnO6 octahedra. All Ag–O bond lengths are 2.49 Å. There are two inequivalent Sn4+ sites. In the first Sn4+ site, Sn4+ is bonded to six equivalent O2- atoms to form SnO6 octahedra that share edges with three equivalent AgO6 octahedra and edges with three equivalent SnO6 octahedra. All Sn–O bond lengths are 2.11 Å. In the second Sn4+ site, Sn4+ is bonded to six equivalent O2- atoms to form SnO6 octahedra that share edges with three equivalent AgO6 octahedra and edges with three equivalent SnO6 octahedra. All Sn–O bond lengths are 2.11 Å. O2- is bonded to two Ag1+ and two Sn4+ atoms to form a mixture of distorted corner and edge-sharing OAg2Sn2 trigonal pyramids.
