(Rb)2KTlI6 is High-temperature superconductor-derived structured and crystallizes in the cubic Fm-3m space group. The structure consists of eight 7440-17-7 atoms inside a KTlI6 framework. In the KTlI6 framework, K(1) is bonded to six equivalent I(1) atoms to form KI6 octahedra that share corners with six equivalent Tl(1)I6 octahedra. The corner-sharing octahedra are not tilted. Tl(1) is bonded to six equivalent I(1) atoms to form TlI6 octahedra that share corners with six equivalent K(1)I6 octahedra. The corner-sharing octahedra are not tilted. I(1) is bonded in a linear geometry to one K(1) and one Tl(1) atom.
