Materials Data on ScAgO2 by Materials Project

Abstract

ScAgO2 crystallizes in the trigonal R3m space group. The structure is three-dimensional. Sc3+ is bonded to six O2- atoms to form edge-sharing ScO6 octahedra. There are three shorter (2.10 Å) and three longer (2.17 Å) Sc–O bond lengths. Ag1+ is bonded in a 1-coordinate geometry to four O2- atoms. There are one shorter (2.18 Å) and three longer (2.59 Å) Ag–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to three equivalent Sc3+ and one Ag1+ atom to form distorted corner-sharing OSc3Ag tetrahedra. In the second O2- site, O2- is bonded in a 6-coordinate geometry to three equivalent Sc3+ and three equivalent Ag1+ atoms.
