K2ScAgI6 crystallizes in the cubic Fm-3m space group. K(1) is bonded to twelve equivalent I(1) atoms to form distorted KI12 cuboctahedra that share corners with twelve equivalent K(1)I12 cuboctahedra, faces with six equivalent K(1)I12 cuboctahedra, faces with four equivalent Sc(1)I6 octahedra, and faces with four equivalent Ag(1)I6 octahedra. Sc(1) is bonded to six equivalent I(1) atoms to form ScI6 octahedra that share corners with six equivalent Ag(1)I6 octahedra and faces with eight equivalent K(1)I12 cuboctahedra. The corner-sharing octahedra are not tilted. Ag(1) is bonded to six equivalent I(1) atoms to form AgI6 octahedra that share corners with six equivalent Sc(1)I6 octahedra and faces with eight equivalent K(1)I12 cuboctahedra. The corner-sharing octahedra are not tilted. I(1) is bonded in a linear geometry to four equivalent K(1), one Sc(1), and one Ag(1) atom.
