K5Te3 crystallizes in the tetragonal I4/m space group. There are three inequivalent K sites. In the first K site, K(1) is bonded in a 4-coordinate geometry to four equivalent Te(1) atoms. In the second K site, K(2) is bonded in a 6-coordinate geometry to two equivalent Te(2) and four equivalent Te(1) atoms. In the third K site, K(3) is bonded in a 6-coordinate geometry to two equivalent Te(2) and four equivalent Te(1) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 10-coordinate geometry to two equivalent K(1), four equivalent K(2), and four equivalent K(3) atoms. In the second Te site, Te(2) is bonded in a 9-coordinate geometry to four equivalent K(2), four equivalent K(3), and one Te(2) atom.
K5Te3 crystallizes in the tetragonal I4/m space group. There are three inequivalent K sites. In the first K site, K(1) is bonded in a 4-coordinate geometry to four equivalent Te(1) atoms. All K(1)-Te(1) bond lengths are 3.43 Å. In the second K site, K(2) is bonded in a 6-coordinate geometry to two equivalent Te(2) and four equivalent Te(1) atoms. Both K(2)-Te(2) bond lengths are 3.71 Å. There is one shorter (3.63 Å) and three longer (3.77 Å) K(2)-Te(1) bond lengths. In the third K site, K(3) is bonded in a 6-coordinate geometry to two equivalent Te(2) and four equivalent Te(1) atoms. Both K(3)-Te(2) bond lengths are 3.62 Å. There are a spread of K(3)-Te(1) bond distances ranging from 3.62-3.79 Å. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 10-coordinate geometry to two equivalent K(1), four equivalent K(2), and four equivalent K(3) atoms. In the second Te site, Te(2) is bonded in a 9-coordinate geometry to four equivalent K(2), four equivalent K(3), and one Te(2) atom. The Te(2)-Te(2) bond length is 2.83 Å.
