Materials Data on NiAgO2 by Materials Project
AgNiO2 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Ni3+ is bonded to six equivalent O2- atoms to form edge-sharing NiO6 octahedra. All Ni–O bond lengths are 2.00 Å. Ag1+ is bonded in a linear geometry to two equivalent O2- atoms. Both Ag–O bond lengths are 2.07 Å. O2- is bonded to three equivalent Ni3+ and one Ag1+ atom to form a mixture of distorted corner and edge-sharing ONi3Ag tetrahedra.
