The material described by Mn3IrGe crystallizes in the cubic P2_13 space group. Mn(1) is bonded in a 12-coordinate geometry to six equivalent Mn(1), three equivalent Ir(1), and three equivalent Ge(1) atoms. Ir(1) is bonded to nine equivalent Mn(1) and three equivalent Ge(1) atoms to form IrMn9Ge3 cuboctahedra that share corners with six equivalent Ir(1)Mn9Ge3 cuboctahedra, corners with nine equivalent Ge(1)Mn9Ir3 cuboctahedra, faces with four equivalent Ge(1)Mn9Ir3 cuboctahedra, and faces with six equivalent Ir(1)Mn9Ge3 cuboctahedra. Ge(1) is bonded to nine equivalent Mn(1) and three equivalent Ir(1) atoms to form GeMn9Ir3 cuboctahedra that share corners with six equivalent Ge(1)Mn9Ir3 cuboctahedra, corners with nine equivalent Ir(1)Mn9Ge3 cuboctahedra, faces with four equivalent Ir(1)Mn9Ge3 cuboctahedra, and faces with six equivalent Ge(1)Mn9Ir3 cuboctahedra. is represented by the CIF file [CIF]
