The crystal structure described by U3Ir3Sb4 crystallizes in the cubic I-43d space group. U(1) is bonded in a 12-coordinate geometry to four equivalent Ir(1) and eight equivalent Sb(1) atoms. Ir(1) is bonded in a 8-coordinate geometry to four equivalent U(1) and four equivalent Sb(1) atoms. Sb(1) is bonded in a 9-coordinate geometry to six equivalent U(1) and three equivalent Ir(1) atoms. is represented by the CIF card [CIF]
