Na3W is Uranium Silicide-like 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 W(1) atoms to form a mixture of distorted corner and edge-sharing NaW4 cuboctahedra. In the second Na site, Na(2) is bonded in a distorted square co-planar geometry to four equivalent W(1) atoms. W(1) is bonded to four equivalent Na(2) and eight equivalent Na(1) atoms to form a mixture of corner, face, and edge-sharing WNa12 cuboctahedra.

In the first Na site, Na(1) is bonded to four equivalent W(1) atoms to form a mixture of distorted corner and edge-sharing NaW4 cuboctahedra. All Na(1)-W(1) bond lengths are 3.43 Å. In the second Na site, Na(2) is bonded in a distorted square co-planar geometry to four equivalent W(1) atoms. All Na(2)-W(1) bond lengths are 3.46 Å. W(1) is bonded to four equivalent Na(2) and eight equivalent Na(1) atoms to form a mixture of corner, face, and edge-sharing WNa12 cuboctahedra.
