(Rb)2YHgI6 crystallizes in the cubic Fm-3m space group. The structure consists of eight 7440-17-7 atoms inside a YHgI6 framework. In the YHgI6 framework, Y(1) is bonded to six equivalent I(1) atoms to form YI6 octahedra that share corners with six equivalent Hg(1)I6 octahedra. The corner-sharing octahedra are not tilted. Hg(1) is bonded to six equivalent I(1) atoms to form HgI6 octahedra that share corners with six equivalent Y(1)I6 octahedra. The corner-sharing octahedra are not tilted. I(1) is bonded in a linear geometry to one Y(1) and one Hg(1) atom.
