The crystal structure described by Ce(IrSn)2 crystallizes in the tetragonal P4/nmm space group. Ce(1) is bonded in a 16-coordinate geometry to four equivalent Ir(1), four equivalent Ir(2), four equivalent Sn(1), and four equivalent Sn(2) atoms. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1), one Sn(1), and four equivalent Sn(2) atoms. In the second Ir site, Ir(2) is bonded to four equivalent Ce(1) and four equivalent Sn(1) atoms to form distorted IrCe4Sn4 tetrahedra that share corners with twelve equivalent Sn(2)Ce4Ir4 tetrahedra, edges with two equivalent Sn(2)Ce4Ir4 tetrahedra, edges with four equivalent Ir(2)Ce4Sn4 tetrahedra, and faces with four equivalent Ir(2)Ce4Sn4 tetrahedra. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1), one Ir(1), and four equivalent Ir(2) atoms. In the second Sn site, Sn(2) is bonded to four equivalent Ce(1) and four equivalent Ir(1) atoms to form distorted SnCe4Ir4 tetrahedra that share corners with twelve equivalent Ir(2)Ce4Sn4 tetrahedra, edges with two equivalent Ir(2)Ce4Sn4 tetrahedra, edges with four equivalent Sn(2)Ce4Ir4 tetrahedra, and faces with four equivalent Sn(2)Ce4Ir4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
