Materials Data on CoAgO2 by Materials Project
AgCoO2 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Co3+ is bonded to six equivalent O2- atoms to form edge-sharing CoO6 octahedra. All Co–O bond lengths are 1.93 Å. Ag1+ is bonded in a linear geometry to two equivalent O2- atoms. Both Ag–O bond lengths are 2.14 Å. O2- is bonded to three equivalent Co3+ and one Ag1+ atom to form a mixture of distorted edge and corner-sharing OCo3Ag tetrahedra.
