The material structure described by Er2CoAl4Ge2 crystallizes in the tetragonal I4/mmm space group. Er(1) is bonded in a 9-coordinate geometry to four equivalent Al(1) and five equivalent Ge(1) atoms. Co(1) is bonded in a body-centered cubic geometry to eight equivalent Al(1) atoms. Al(1) is bonded in a 11-coordinate geometry to two equivalent Er(1), two equivalent Co(1), five equivalent Al(1), and two equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to five equivalent Er(1) and four equivalent Al(1) atoms. is represented by the CIF card [CIF]
