The compound described by Na3AgO2 crystallizes in the orthorhombic Ibam space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded to four equivalent O(1) atoms to form a mixture of edge and corner-sharing NaO4 tetrahedra. In the second Na site, Na(2) is bonded to four equivalent O(1) atoms to form a mixture of distorted edge and corner-sharing NaO4 tetrahedra. Ag(1) is bonded in a linear geometry to two equivalent O(1) atoms. O(1) is bonded to two equivalent Na(2), four equivalent Na(1), and one Ag(1) atom to form a mixture of distorted edge and corner-sharing ONa6Ag hexagonal pyramids. is represented by the CIF file [CIF]
