The material described by AgNiO2 crystallizes in the trigonal R-3m space group. Ni(1) is bonded to six equivalent O(1) atoms to form edge-sharing NiO6 octahedra. Ag(1) is bonded in a linear geometry to two equivalent O(1) atoms. O(1) is bonded to three equivalent Ni(1) and one Ag(1) atom to form a mixture of distorted corner and edge-sharing ONi3Ag tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
