The crystal structure described by ErSmNi2 crystallizes in the orthorhombic Amm2 space group. Er(1) is bonded in a 7-coordinate geometry to three equivalent Ni(1) and four equivalent Ni(2) atoms. Sm(1) is bonded in a 7-coordinate geometry to three equivalent Ni(2) and four equivalent Ni(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to three equivalent Er(1), four equivalent Sm(1), and two equivalent Ni(2) atoms. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to four equivalent Er(1), three equivalent Sm(1), and two equivalent Ni(1) atoms. is represented by the CIF card [CIF]
