The structure described by U2RuGa8 crystallizes in the tetragonal P4/mmm space group. U(1) is bonded to four equivalent Ga(1), four equivalent Ga(2), and four equivalent Ga(3) atoms to form UGa12 cuboctahedra that share corners with eight equivalent U(1)Ga12 cuboctahedra, edges with four equivalent Ga(2)U4Ga8 cuboctahedra, edges with eight equivalent Ga(1)U4Ga8 cuboctahedra, faces with four equivalent Ga(1)U4Ga8 cuboctahedra, faces with four equivalent Ga(2)U4Ga8 cuboctahedra, and faces with five equivalent U(1)Ga12 cuboctahedra. Ru(1) is bonded in a body-centered cubic geometry to eight equivalent Ga(3) atoms. There are three inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to four equivalent U(1), four equivalent Ga(1), and four equivalent Ga(2) atoms to form distorted GaU4Ga8 cuboctahedra that share corners with four equivalent Ga(1)U4Ga8 cuboctahedra, edges with eight equivalent U(1)Ga12 cuboctahedra, edges with eight equivalent Ga(2)U4Ga8 cuboctahedra, faces with four equivalent U(1)Ga12 cuboctahedra, faces with four equivalent Ga(2)U4Ga8 cuboctahedra, and faces with eight equivalent Ga(1)U4Ga8 cuboctahedra. In the second Ga site, Ga(2) is bonded to four equivalent U(1), four equivalent Ga(1), and four equivalent Ga(3) atoms to form GaU4Ga8 cuboctahedra that share corners with eight equivalent Ga(2)U4Ga8 cuboctahedra, edges with four equivalent U(1)Ga12 cuboctahedra, edges with eight equivalent Ga(1)U4Ga8 cuboctahedra, faces with four equivalent U(1)Ga12 cuboctahedra, faces with four equivalent Ga(1)U4Ga8 cuboctahedra, and faces with five equivalent Ga(2)U4Ga8 cuboctahedra. In the third Ga site, Ga(3) is bonded in a 4-coordinate geometry to two equivalent U(1), two equivalent Ru(1), and two equivalent Ga(2) atoms. is represented by the CIF card [CIF]
