Y7(AuTe)2 crystallizes in the orthorhombic Imm2 space group. There are four inequivalent Y sites. In the first Y site, Y(1) is bonded to two equivalent Au(1), one Te(2), and two equivalent Te(1) atoms to form a mixture of distorted corner, edge, and face-sharing YTe3Au2 trigonal bipyramids. In the second Y site, Y(2) is bonded in a 4-coordinate geometry to three equivalent Au(1) and one Te(1) atom. In the third Y site, Y(3) is bonded in a 4-coordinate geometry to two equivalent Au(1) and two equivalent Te(2) atoms. In the fourth Y site, Y(4) is bonded in a 3-coordinate geometry to one Te(2) and two equivalent Te(1) atoms. Au(1) is bonded in a 7-coordinate geometry to two equivalent Y(1), two equivalent Y(3), and three equivalent Y(2) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 8-coordinate geometry to two equivalent Y(2), two equivalent Y(4), and four equivalent Y(1) atoms. In the second Te site, Te(2) is bonded in a 7-coordinate geometry to one Y(4), two equivalent Y(1), and four equivalent Y(3) atoms.

In the first Y site, Y(1) is bonded to two equivalent Au(1), one Te(2), and two equivalent Te(1) atoms to form a mixture of distorted corner, edge, and face-sharing YTe3Au2 trigonal bipyramids. Both Y(1)-Au(1) bond lengths are 2.94 Å. The Y(1)-Te(2) bond length is 3.14 Å. Both Y(1)-Te(1) bond lengths are 3.20 Å. In the second Y site, Y(2) is bonded in a 4-coordinate geometry to three equivalent Au(1) and one Te(1) atom. There are two shorter (2.93 Å) and one longer (3.20 Å) Y(2)-Au(1) bond length. The Y(2)-Te(1) bond length is 3.18 Å. In the third Y site, Y(3) is bonded in a 4-coordinate geometry to two equivalent Au(1) and two equivalent Te(2) atoms. Both Y(3)-Au(1) bond lengths are 2.98 Å.
