The structure described by ErNiSn crystallizes in the orthorhombic Pnma space group. Er(1) is bonded in a 12-coordinate geometry to six equivalent Ni(1) and six equivalent Sn(1) atoms. Ni(1) is bonded in a 10-coordinate geometry to six equivalent Er(1) and four equivalent Sn(1) atoms. Sn(1) is bonded in a 10-coordinate geometry to six equivalent Er(1) and four equivalent Ni(1) atoms. is represented by the CIF card [CIF]
