The structure described by Gd2CoGa8 crystallizes in the tetragonal P4/mmm space group. Gd(1) is bonded to four equivalent Ga(1), four equivalent Ga(2), and four equivalent Ga(3) atoms to form GdGa12 cuboctahedra that share corners with eight equivalent Gd(1)Ga12 cuboctahedra, edges with eight equivalent Ga(2)Gd4Ga8 cuboctahedra, faces with four equivalent Ga(2)Gd4Ga8 cuboctahedra, and faces with five equivalent Gd(1)Ga12 cuboctahedra. Co(1) is bonded in a body-centered cubic geometry to eight equivalent Ga(1) atoms. There are three inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 11-coordinate geometry to two equivalent Gd(1), two equivalent Co(1), two equivalent Ga(3), and five equivalent Ga(1) atoms. In the second Ga site, Ga(2) is bonded to four equivalent Gd(1), four equivalent Ga(2), and four equivalent Ga(3) atoms to form distorted GaGd4Ga8 cuboctahedra that share corners with four equivalent Ga(2)Gd4Ga8 cuboctahedra, edges with eight equivalent Gd(1)Ga12 cuboctahedra, faces with four equivalent Gd(1)Ga12 cuboctahedra, and faces with eight equivalent Ga(2)Gd4Ga8 cuboctahedra. In the third Ga site, Ga(3) is bonded in a distorted rectangular see-saw-like geometry to four equivalent Gd(1), four equivalent Ga(1), and four equivalent Ga(2) atoms. is represented by the CIF file [CIF]
