Materials Data on Rb2PtI6 by Materials Project

Rb2PtI6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Rb1+ is bonded to twelve equivalent I1- atoms to form RbI12 cuboctahedra that share corners with twelve equivalent RbI12 cuboctahedra, faces with six equivalent RbI12 cuboctahedra, and faces with four equivalent PtI6 octahedra. All Rb–I bond lengths are 4.08 Å. Pt4+ is bonded to six equivalent I1- atoms to form PtI6 octahedra that share faces with eight equivalent RbI12 cuboctahedra. All Pt–I bond lengths are 2.71 Å. I1- is bonded to four equivalent Rb1+ and one Pt4+ atom to form a mixture of distorted face, edge, and corner-sharing IRb4Pt square pyramids.

Materials Data on Rb2PtI5 by Materials Project

Rb2PtI5 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Rb is bonded in a 8-coordinate geometry to eight I atoms. There are a spread of Rb–I bond distances ranging from 3.80–4.23 Å. Pt is bonded to six I atoms to form corner-sharing PtI6 octahedra. The corner-sharing octahedral tilt angles are 13°. There are a spread of Pt–I bond distances ranging from 2.68–2.93 Å. There are three inequivalent I sites. In the first I site, I is bonded to four equivalent Rb and one Pt atom to form a mixture of distorted edge and corner-sharing IRb4Pt trigonal bipyramids. In the second I site, I is bonded in a 6-coordinate geometry to four equivalent Rb and two equivalent Pt atoms. In the third I site, I is bonded in a 3-coordinate geometry to two equivalent Rb and one Pt atom.
