The structure described by Be4AlMn crystallizes in the cubic F-43m space group. Be(1) is bonded to six equivalent Be(1), three equivalent Mn(1), and three equivalent Al(1) atoms to form a mixture of corner, face, and edge-sharing BeMn3Be6Al3 cuboctahedra. Mn(1) is bonded in a 16-coordinate geometry to twelve equivalent Be(1) and four equivalent Al(1) atoms. Al(1) is bonded in a 16-coordinate geometry to twelve equivalent Be(1) and four equivalent Mn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
