The material described by Lu7(NiTe)2 crystallizes in the orthorhombic Imm2 space group. There are four inequivalent Lu sites. In the first Lu site, Lu(1) is bonded in a 4-coordinate geometry to three equivalent Ni(1) and one Te(2) atom. In the second Lu site, Lu(2) is bonded in a 3-coordinate geometry to one Te(1) and two equivalent Te(2) atoms. In the third Lu site, Lu(3) is bonded in a 5-coordinate geometry to two equivalent Ni(1), one Te(1), and two equivalent Te(2) atoms. In the fourth Lu site, Lu(4) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Ni(1) and two equivalent Te(1) atoms. Ni(1) is bonded in a 7-coordinate geometry to two equivalent Lu(3), two equivalent Lu(4), and three equivalent Lu(1) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 7-coordinate geometry to one Lu(2), two equivalent Lu(3), and four equivalent Lu(4) atoms. In the second Te site, Te(2) is bonded in a 8-coordinate geometry to two equivalent Lu(1), two equivalent Lu(2), and four equivalent Lu(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
