The compound described by AgFeO2 crystallizes in the trigonal R-3m space group. Fe(1) is bonded to six equivalent O(1) atoms to form edge-sharing FeO6 octahedra. Ag(1) is bonded in a linear geometry to two equivalent O(1) atoms. O(1) is bonded to three equivalent Fe(1) and one Ag(1) atom to form a mixture of distorted edge and corner-sharing OFe3Ag tetrahedra. is represented by the CIF file [CIF]
