The structure described by Er(MoAl2)2 crystallizes in the tetragonal I4/mmm space group. Er(1) is bonded in a 4-coordinate geometry to twelve Al(1,1,1,1) atoms. Mo(1) is bonded in a 10-coordinate geometry to two equivalent Mo(1) and eight Al(1,1,1,1) atoms. There are four inequivalent Al sites. In the first Al site, Al(1) is bonded in a 11-coordinate geometry to three equivalent Er(1), four equivalent Mo(1), and four equivalent Al(1) atoms. In the second Al site, Al(1) is bonded in a 11-coordinate geometry to three equivalent Er(1); four equivalent Mo(1); and four Al(1,1,1) atoms. In the third Al site, Al(1) is bonded in a 11-coordinate geometry to three equivalent Er(1), four equivalent Mo(1), and four equivalent Al(1) atoms. In the fourth Al site, Al(1) is bonded in a 11-coordinate geometry to three equivalent Er(1), four equivalent Mo(1), and four equivalent Al(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
