IrMnAl is half-Heusler structured and crystallizes in the cubic F-43m space group. Mn(1) is bonded to four equivalent Ir(1) atoms to form MnIr4 tetrahedra that share corners with four equivalent Al(1)Ir4 tetrahedra, corners with twelve equivalent Mn(1)Ir4 tetrahedra, and edges with six equivalent Al(1)Ir4 tetrahedra. Ir(1) is bonded in a body-centered cubic geometry to four equivalent Mn(1) and four equivalent Al(1) atoms. Al(1) is bonded to four equivalent Ir(1) atoms to form AlIr4 tetrahedra that share corners with four equivalent Mn(1)Ir4 tetrahedra, corners with twelve equivalent Al(1)Ir4 tetrahedra, and edges with six equivalent Mn(1)Ir4 tetrahedra.
