NaGa4 crystallizes in the tetragonal I4/mmm space group. Na(1) is bonded in a 16-coordinate geometry to eight equivalent Ga(1) and eight equivalent Ga(2) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to four equivalent Na(1), four equivalent Ga(1), and four equivalent Ga(2) atoms to form a mixture of edge, face, and corner-sharing GaNa4Ga8 cuboctahedra. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to four equivalent Na(1), one Ga(2), and four equivalent Ga(1) atoms.
