The compound described by U2Ir2Sn crystallizes in the tetragonal P4/mbm space group. U(1) is bonded in a 6-coordinate geometry to six equivalent Ir(1) and four equivalent Sn(1) atoms. Ir(1) is bonded in a 8-coordinate geometry to six equivalent U(1) and two equivalent Sn(1) atoms. Sn(1) is bonded to eight equivalent U(1) and four equivalent Ir(1) atoms to form a mixture of face and corner-sharing SnU8Ir4 cuboctahedra. is represented by the CIF card [CIF]
