The crystal structure described by Na3AuO3 crystallizes in the tetragonal P4_2/mnm space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded to one O(1) and four equivalent O(2) atoms to form distorted NaO5 trigonal bipyramids that share corners with three equivalent Na(1)O5 trigonal bipyramids, corners with two equivalent Na(2)O4 trigonal pyramids, edges with five equivalent Na(1)O5 trigonal bipyramids, and edges with two equivalent Na(2)O4 trigonal pyramids. In the second Na site, Na(2) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form distorted NaO4 trigonal pyramids that share corners with four equivalent Na(1)O5 trigonal bipyramids, corners with two equivalent Na(2)O4 trigonal pyramids, and edges with four equivalent Na(1)O5 trigonal bipyramids. Au(1) is bonded in a rectangular see-saw-like geometry to two equivalent O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Na(1), two equivalent Na(2), and two equivalent Au(1) atoms to form ONa4Au2 octahedra that share corners with two equivalent O(1)Na4Au2 octahedra, corners with four equivalent O(2)Na5Au octahedra,  an edgeedge with one O(1)Na4Au2 octahedra, and edges with six equivalent O(2)Na5Au octahedra. The corner-sharing octahedral tilt angles range from 4-26°. In the second O site, O(2) is bonded to one Na(2), four equivalent Na(1), and one Au(1) atom to form distorted ONa5Au octahedra that share corners with two equivalent O(1)Na4Au2 octahedra, corners with two equivalent O(2)Na5Au octahedra, edges with three equivalent O(1)Na4Au2 octahedra, and edges with six equivalent O(2)Na5Au octahedra. The corner-sharing octahedral tilt angles range from 4-23°. is represented by the Crystallographic Information File (CIF) [CIF]
