K2TeI6 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 8-coordinate geometry to two equivalent I(1), three equivalent I(2), and three equivalent I(3) atoms. Te(1) is bonded in an octahedral geometry to two equivalent I(1), two equivalent I(2), and two equivalent I(3) atoms. There are three inequivalent I sites. In the first I site, I(1) is bonded in a trigonal non-coplanar geometry to two equivalent K(1) and one Te(1) atom. In the second I site, I(2) is bonded to three equivalent K(1) and one Te(1) atom to form a mixture of distorted corner and edge-sharing IK3Te trigonal pyramids. In the third I site, I(3) is bonded in a distorted see-saw-like geometry to three equivalent K(1) and one Te(1) atom.
