Na3Au is alpha bismuth trifluoride structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded to four equivalent Na(2) and four equivalent Au(1) atoms to form a mixture of distorted edge, face, and corner-sharing NaNa4Au4 tetrahedra. In the second Na site, Na(2) is bonded in a 14-coordinate geometry to eight equivalent Na(1) and six equivalent Au(1) atoms. Au(1) is bonded in a distorted body-centered cubic geometry to six equivalent Na(2) and eight equivalent Na(1) atoms.

In the first Na site, Na(1) is bonded to four equivalent Na(2) and four equivalent Au(1) atoms to form a mixture of distorted edge, face, and corner-sharing NaNa4Au4 tetrahedra. All Na(1)-Na(2) bond lengths are 3.13 Å. All Na(1)-Au(1) bond lengths are 3.13 Å. In the second Na site, Na(2) is bonded in a 14-coordinate geometry to eight equivalent Na(1) and six equivalent Au(1) atoms. There are four shorter (3.57 Å) and two longer (3.71 Å) Na(2)-Au(1) bond lengths. Au(1) is bonded in a distorted body-centered cubic geometry to six equivalent Na(2) and eight equivalent Na(1) atoms.
