MnAl is Tetraauricupride structured and crystallizes in the tetragonal P4/mmm space group. Mn(1) is bonded to four equivalent Mn(1) and eight equivalent Al(1) atoms to form MnMn4Al8 cuboctahedra that share corners with twelve equivalent Mn(1)Mn4Al8 cuboctahedra, edges with eight equivalent Mn(1)Mn4Al8 cuboctahedra, edges with sixteen equivalent Al(1)Mn8Al4 cuboctahedra, faces with eight equivalent Al(1)Mn8Al4 cuboctahedra, and faces with ten equivalent Mn(1)Mn4Al8 cuboctahedra. Al(1) is bonded to eight equivalent Mn(1) and four equivalent Al(1) atoms to form AlMn8Al4 cuboctahedra that share corners with twelve equivalent Al(1)Mn8Al4 cuboctahedra, edges with eight equivalent Al(1)Mn8Al4 cuboctahedra, edges with sixteen equivalent Mn(1)Mn4Al8 cuboctahedra, faces with eight equivalent Mn(1)Mn4Al8 cuboctahedra, and faces with ten equivalent Al(1)Mn8Al4 cuboctahedra.
