The structure described by Rb2PtI5 crystallizes in the orthorhombic Cmcm space group. Rb(1) is bonded in a 7-coordinate geometry to one I(3), two equivalent I(2), and four equivalent I(1) atoms. Pt(1) is bonded to two equivalent I(1), two equivalent I(2), and two equivalent I(3) atoms to form corner-sharing PtI6 octahedra. The corner-sharing octahedral tilt angles are 10°. There are three inequivalent I sites. In the first I site, I(1) is bonded to four equivalent Rb(1) and one Pt(1) atom to form a mixture of distorted corner and edge-sharing IRb4Pt trigonal bipyramids. In the second I site, I(2) is bonded in a 3-coordinate geometry to two equivalent Rb(1) and one Pt(1) atom. In the third I site, I(3) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Rb(1) and two equivalent Pt(1) atoms. is represented by the CIF file [CIF]
