Yb2IrIn8 crystallizes in the tetragonal P4/mmm space group. Yb(1) is bonded to four equivalent In(1), four equivalent In(2), and four equivalent In(3) atoms to form YbIn12 cuboctahedra that share corners with eight equivalent Yb(1)In12 cuboctahedra, edges with four equivalent In(2)Yb4In8 cuboctahedra, edges with eight equivalent In(3)Yb4In8 cuboctahedra, faces with four equivalent In(2)Yb4In8 cuboctahedra, faces with four equivalent In(3)Yb4In8 cuboctahedra, and faces with five equivalent Yb(1)In12 cuboctahedra. Ir(1) is bonded in a body-centered cubic geometry to eight equivalent In(1) atoms. There are three inequivalent In sites. In the first In site, In(1) is bonded in a 4-coordinate geometry to two equivalent Yb(1), two equivalent Ir(1), and two equivalent In(2) atoms. In the second In site, In(2) is bonded to four equivalent Yb(1), four equivalent In(1), and four equivalent In(3) atoms to form distorted InYb4In8 cuboctahedra that share corners with eight equivalent In(2)Yb4In8 cuboctahedra, edges with four equivalent Yb(1)In12 cuboctahedra, edges with eight equivalent In(3)Yb4In8 cuboctahedra, faces with four equivalent Yb(1)In12 cuboctahedra, faces with four equivalent In(3)Yb4In8 cuboctahedra, and faces with five equivalent In(2)Yb4In8 cuboctahedra. In the third In site, In(3) is bonded to four equivalent Yb(1), four equivalent In(2), and four equivalent In(3) atoms to form distorted InYb4In8 cuboctahedra that share corners with four equivalent In(3)Yb4In8 cuboctahedra, edges with eight equivalent Yb(1)In12 cuboctahedra, edges with eight equivalent In(2)Yb4In8 cuboctahedra, faces with four equivalent Yb(1)In12 cuboctahedra, faces with four equivalent In(2)Yb4In8 cuboctahedra, and faces with eight equivalent In(3)Yb4In8 cuboctahedra.
