The material described by ErNiAl2 crystallizes in the orthorhombic Cmcm space group. Er(1) is bonded in a 13-coordinate geometry to three equivalent Ni(1) and ten equivalent Al(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to three equivalent Er(1) and six equivalent Al(1) atoms. Al(1) is bonded in a 3-coordinate geometry to five equivalent Er(1) and three equivalent Ni(1) atoms. is represented by the CIF card [CIF]
