Materials Data on Na3AgO2 by Materials Project
Na3AgO2 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to four equivalent O2- atoms to form a mixture of edge and corner-sharing NaO4 tetrahedra. There are two shorter (2.39 Å) and two longer (2.42 Å) Na–O bond lengths. In the second Na1+ site, Na1+ is bonded to four equivalent O2- atoms to form a mixture of edge and corner-sharing NaO4 tetrahedra. All Na–O bond lengths are 2.46 Å. Ag1+ is bonded in a linear geometry to two equivalent O2- atoms. Both Ag–O bond lengths are 2.13 Å. O2- is bonded to six Na1+ and one Ag1+ atom to form a mixture of distorted edge and corner-sharing ONa6Ag hexagonal pyramids.
