Materials Data on CrAgO2 by Materials Project

AgCrO2 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Cr3+ is bonded to six equivalent O2- atoms to form edge-sharing CrO6 octahedra. All Cr–O bond lengths are 2.03 Å. Ag1+ is bonded in a linear geometry to two equivalent O2- atoms. Both Ag–O bond lengths are 2.12 Å. O2- is bonded to three equivalent Cr3+ and one Ag1+ atom to form a mixture of distorted edge and corner-sharing OCr3Ag tetrahedra.

Materials Data on CrAgO2 by Materials Project

AgCrO2 crystallizes in the trigonal R3m space group. The structure is three-dimensional. Cr3+ is bonded to six O2- atoms to form edge-sharing CrO6 octahedra. There are three shorter (2.02 Å) and three longer (2.05 Å) Cr–O bond lengths. Ag1+ is bonded in a 1-coordinate geometry to four O2- atoms. There are one shorter (2.19 Å) and three longer (2.60 Å) Ag–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to three equivalent Cr3+ and one Ag1+ atom to form distorted corner-sharing OCr3Ag tetrahedra. In the second O2- site, O2- is bonded in a 6-coordinate geometry to three equivalent Cr3+ and three equivalent Ag1+ atoms.
