The material structure described by KTc2Fe crystallizes in the cubic F-43m space group. K(1) is bonded in a distorted body-centered cubic geometry to four equivalent Tc(1), six equivalent Tc(2), and four equivalent Fe(1) atoms. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded to four equivalent K(1) and four equivalent Tc(2) atoms to form distorted edge-sharing TcK4Tc4 tetrahedra. In the second Tc site, Tc(2) is bonded in a 14-coordinate geometry to six equivalent K(1), four equivalent Tc(1), and four equivalent Fe(1) atoms. Fe(1) is bonded in a distorted body-centered cubic geometry to four equivalent K(1) and four equivalent Tc(2) atoms. is represented by the CIF file [CIF]
