The compound described by K2TcI6 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 8-coordinate geometry to two equivalent I(2), three equivalent I(1), and three equivalent I(3) atoms. Tc(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 distorted rectangular see-saw-like geometry to three equivalent K(1) and one Tc(1) atom. In the second I site, I(2) is bonded in a distorted trigonal non-coplanar geometry to two equivalent K(1) and one Tc(1) atom. In the third I site, I(3) is bonded in a distorted see-saw-like geometry to three equivalent K(1) and one Tc(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
