The structure described by Mn3Ir is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Mn(1) is bonded to four equivalent Ir(1) atoms to form a mixture of distorted edge, face, and corner-sharing MnIr4 cuboctahedra. Ir(1) is bonded to twelve equivalent Mn(1) atoms to form a mixture of face and corner-sharing IrMn12 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
