K2TcBr6 crystallizes in the cubic Fm-3m space group. K(1) is bonded to twelve equivalent Br(1) atoms to form KBr12 cuboctahedra that share corners with twelve equivalent K(1)Br12 cuboctahedra, faces with six equivalent K(1)Br12 cuboctahedra, and faces with four equivalent Tc(1)Br6 octahedra. Tc(1) is bonded to six equivalent Br(1) atoms to form TcBr6 octahedra that share faces with eight equivalent K(1)Br12 cuboctahedra. Br(1) is bonded to four equivalent K(1) and one Tc(1) atom to form a mixture of distorted corner, face, and edge-sharing BrK4Tc square pyramids.
