The material structure described by HgGa3 crystallizes in the hexagonal P6_3/mmc space group. Hg(1) is bonded to twelve Ga(1,1) atoms to form a mixture of face and corner-sharing HgGa12 cuboctahedra. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 12-coordinate geometry to four equivalent Hg(1) and eight Ga(1,1) atoms. In the second Ga site, Ga(1) is bonded in a 12-coordinate geometry to four equivalent Hg(1) and eight equivalent Ga(1) atoms. is represented by the CIF file [CIF]
