The material described by Lu7Te crystallizes in the orthorhombic Cmcm space group. There are four inequivalent Lu sites. In the first Lu site, Lu(1) is bonded in a distorted single-bond geometry to four equivalent Lu(3) and one Te(1) atom. In the second Lu site, Lu(2) is bonded in a 2-coordinate geometry to three equivalent Lu(3) and two equivalent Te(1) atoms. In the third Lu site, Lu(3) is bonded to three equivalent Lu(2), four equivalent Lu(1), and five equivalent Lu(3) atoms to form a mixture of distorted edge, face, and corner-sharing LuLu12 cuboctahedra. In the fourth Lu site, Lu(4) is bonded in a 3-coordinate geometry to three equivalent Te(1) atoms. Te(1) is bonded in a 9-coordinate geometry to two equivalent Lu(1), three equivalent Lu(4), and four equivalent Lu(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
