K8SrTe6 crystallizes in the tetragonal I-42m space group. K(1) is bonded in a 6-coordinate geometry to two equivalent Te(1) and four equivalent Te(2) atoms. Sr(1) is bonded in a distorted tetrahedral geometry to four equivalent Te(2) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 10-coordinate geometry to eight equivalent K(1) and two equivalent Te(1) atoms. In the second Te site, Te(2) is bonded in a 9-coordinate geometry to eight equivalent K(1) and one Sr(1) atom.
K8SrTe6 crystallizes in the tetragonal I-42m space group. K(1) is bonded in a 6-coordinate geometry to two equivalent Te(1) and four equivalent Te(2) atoms. There is one shorter (3.58 Å) and one longer (3.63 Å) K(1)-Te(1) bond length. There are a spread of K(1)-Te(2) bond distances ranging from 3.63-3.70 Å. Sr(1) is bonded in a distorted tetrahedral geometry to four equivalent Te(2) atoms. All Sr(1)-Te(2) bond lengths are 3.26 Å. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 10-coordinate geometry to eight equivalent K(1) and two equivalent Te(1) atoms. Both Te(1)-Te(1) bond lengths are 3.11 Å. In the second Te site, Te(2) is bonded in a 9-coordinate geometry to eight equivalent K(1) and one Sr(1) atom.
