Rb2PdI6 crystallizes in the cubic Fm-3m space group. Rb(1) is bonded to twelve equivalent I(1) atoms to form RbI12 cuboctahedra that share corners with twelve equivalent Rb(1)I12 cuboctahedra, faces with six equivalent Rb(1)I12 cuboctahedra, and faces with four equivalent Pd(1)I6 octahedra. Pd(1) is bonded to six equivalent I(1) atoms to form PdI6 octahedra that share faces with eight equivalent Rb(1)I12 cuboctahedra. I(1) is bonded to four equivalent Rb(1) and one Pd(1) atom to form a mixture of distorted edge, face, and corner-sharing IRb4Pd square pyramids.
