The compound described by Er5Ni2Te2 crystallizes in the orthorhombic Cmcm space group. There are three inequivalent Er sites. In the first Er site, Er(1) is bonded in a 7-coordinate geometry to one Ni(2), two equivalent Ni(1), and four equivalent Te(1) atoms. In the second Er site, Er(2) is bonded in a 6-coordinate geometry to one Ni(1), two equivalent Ni(2), and three equivalent Te(1) atoms. In the third Er site, Er(3) is bonded in a square co-planar geometry to one Ni(1), one Ni(2), and two equivalent Te(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to one Er(3), two equivalent Er(2), four equivalent Er(1), and two equivalent Ni(2) atoms. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to one Er(3), two equivalent Er(1), four equivalent Er(2), and two equivalent Ni(1) atoms. Te(1) is bonded in a 8-coordinate geometry to one Er(3), three equivalent Er(2), and four equivalent Er(1) atoms. is represented by the CIF card [CIF]
