The material structure described by ErZn2 crystallizes in the orthorhombic Imma space group. Er(1) is bonded in a 12-coordinate geometry to twelve equivalent Zn(1) atoms. Zn(1) is bonded in a 10-coordinate geometry to six equivalent Er(1) and four equivalent Zn(1) atoms. is represented by the CIF file [CIF]
