K2TcF6 crystallizes in the trigonal P-3m1 space group. K(1) is bonded to twelve equivalent F(1) atoms to form KF12 cuboctahedra that share corners with six equivalent K(1)F12 cuboctahedra, corners with three equivalent Tc(1)F6 octahedra, faces with eight equivalent K(1)F12 cuboctahedra, and faces with three equivalent Tc(1)F6 octahedra. The corner-sharing octahedral tilt angles are 19°. Tc(1) is bonded to six equivalent F(1) atoms to form TcF6 octahedra that share corners with six equivalent K(1)F12 cuboctahedra and faces with six equivalent K(1)F12 cuboctahedra. F(1) is bonded in a distorted single-bond geometry to four equivalent K(1) and one Tc(1) atom.
