In the first Mo site, Mo is bonded in a 11-coordinate geometry to eleven Al atoms. There are a spread of Mo–Al bond distances ranging from 2.64–2.87 Å. In the second Mo site, Mo is bonded to twelve Al atoms to form MoAl12 cuboctahedra that share corners with five equivalent MoAl12 cuboctahedra, corners with five equivalent AlAl9Mo3 cuboctahedra, edges with four equivalent MoAl12 cuboctahedra, and faces with four equivalent AlAl9Mo3 cuboctahedra.
