The structure described by Lu2CoGa8 crystallizes in the tetragonal P4/mmm space group. Lu(1) is bonded to four Ga(1,1); four equivalent Ga(2); and four equivalent Ga(3) atoms to form LuGa12 cuboctahedra that share corners with eight equivalent Lu(1)Ga12 cuboctahedra, edges with four equivalent Ga(3)Lu4Ga8 cuboctahedra, edges with eight equivalent Ga(2)Lu4Ga8 cuboctahedra, faces with four equivalent Ga(2)Lu4Ga8 cuboctahedra, faces with four equivalent Ga(3)Lu4Ga8 cuboctahedra, and faces with five equivalent Lu(1)Ga12 cuboctahedra. Co(1) is bonded in a body-centered cubic geometry to eight Ga(1,1,1) atoms. There are five inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 11-coordinate geometry to two equivalent Lu(1); two equivalent Co(1); two equivalent Ga(3); and five Ga(1,1) atoms. In the second Ga site, Ga(1) is bonded in a 11-coordinate geometry to two equivalent Lu(1); two equivalent Co(1); two equivalent Ga(3); and five Ga(1,1) atoms. In the third Ga site, Ga(1) is bonded in a 11-coordinate geometry to two equivalent Lu(1); two equivalent Co(1); two equivalent Ga(3); and five Ga(1,1) atoms. In the fourth Ga site, Ga(2) is bonded to four equivalent Lu(1), four equivalent Ga(2), and four equivalent Ga(3) atoms to form distorted GaLu4Ga8 cuboctahedra that share corners with four equivalent Ga(2)Lu4Ga8 cuboctahedra, edges with eight equivalent Lu(1)Ga12 cuboctahedra, edges with eight equivalent Ga(3)Lu4Ga8 cuboctahedra, faces with four equivalent Lu(1)Ga12 cuboctahedra, faces with four equivalent Ga(3)Lu4Ga8 cuboctahedra, and faces with eight equivalent Ga(2)Lu4Ga8 cuboctahedra.
