Na3AuO2 crystallizes in the tetragonal P4_2/mnm space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a linear geometry to two equivalent O(1) atoms. In the second Na site, Na(2) is bonded in a distorted see-saw-like geometry to four equivalent O(1) atoms. Au(1) is bonded in a linear geometry to two equivalent O(1) atoms. O(1) is bonded to one Na(1), four equivalent Na(2), and one Au(1) atom to form a mixture of edge and corner-sharing ONa5Au octahedra. The corner-sharing octahedral tilt angles range from 3-18°.
Na3AuO2 crystallizes in the tetragonal P4_2/mnm space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a linear geometry to two equivalent O(1) atoms. Both Na(1)-O(1) bond lengths are 2.23 Å. In the second Na site, Na(2) is bonded in a distorted see-saw-like geometry to four equivalent O(1) atoms. There are a spread of Na(2)-O(1) bond distances ranging from 2.30-2.35 Å. Au(1) is bonded in a linear geometry to two equivalent O(1) atoms. Both Au(1)-O(1) bond lengths are 2.01 Å. O(1) is bonded to one Na(1), four equivalent Na(2), and one Au(1) atom to form a mixture of edge and corner-sharing ONa5Au octahedra. The corner-sharing octahedral tilt angles range from 3-18°.
