The material described by Y7Te2 crystallizes in the orthorhombic Pnma space group. There are seven inequivalent Y sites. In the first Y site, Y(1) is bonded in a 11-coordinate geometry to one Y(4), one Y(6), two equivalent Y(1), two equivalent Y(2), two equivalent Y(5), and three equivalent Y(3) atoms. In the second Y site, Y(2) is bonded in a 3-coordinate geometry to two equivalent Y(1), one Te(1), and two equivalent Te(2) atoms. In the third Y site, Y(3) is bonded in a 2-coordinate geometry to three equivalent Y(1) and two equivalent Te(1) atoms. In the fourth Y site, Y(4) is bonded in a 3-coordinate geometry to one Y(1), one Te(1), and three equivalent Te(2) atoms. In the fifth Y site, Y(5) is bonded in a distorted single-bond geometry to two equivalent Y(1) and one Te(2) atom. In the sixth Y site, Y(6) is bonded in a single-bond geometry to one Y(1) and one Te(1) atom. In the seventh Y site, Y(7) is bonded in a 4-coordinate geometry to two equivalent Te(1) and two equivalent Te(2) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 7-coordinate geometry to one Y(2), one Y(4), one Y(6), two equivalent Y(3), and two equivalent Y(7) atoms. In the second Te site, Te(2) is bonded in a 8-coordinate geometry to one Y(5), two equivalent Y(2), two equivalent Y(7), and three equivalent Y(4) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
