Cs2PtI6 crystallizes in the cubic Fm-3m space group. Cs(1) is bonded to twelve equivalent I(1) atoms to form CsI12 cuboctahedra that share corners with twelve equivalent Cs(1)I12 cuboctahedra, faces with six equivalent Cs(1)I12 cuboctahedra, and faces with four equivalent Pt(1)I6 octahedra. Pt(1) is bonded to six equivalent I(1) atoms to form PtI6 octahedra that share faces with eight equivalent Cs(1)I12 cuboctahedra. I(1) is bonded to four equivalent Cs(1) and one Pt(1) atom to form a mixture of distorted corner, face, and edge-sharing ICs4Pt square pyramids.
