The crystal structure described by K2TcTl6 crystallizes in the cubic Fm-3m space group. K(1) is bonded to twelve equivalent Tl(1) atoms to form KTl12 cuboctahedra that share corners with twelve equivalent K(1)Tl12 cuboctahedra, faces with six equivalent K(1)Tl12 cuboctahedra, and faces with four equivalent Tc(1)Tl6 octahedra. Tc(1) is bonded to six equivalent Tl(1) atoms to form TcTl6 octahedra that share faces with eight equivalent K(1)Tl12 cuboctahedra. Tl(1) is bonded in a 9-coordinate geometry to four equivalent K(1), one Tc(1), and four equivalent Tl(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
