Materials Data on K2PtBr6 by Materials Project

K2PtBr6 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. K1+ is bonded in a distorted rectangular see-saw-like geometry to eight Br1- atoms. There are a spread of K–Br bond distances ranging from 3.33–4.01 Å. Pt4+ is bonded in a square co-planar geometry to four equivalent Br1- atoms. All Pt–Br bond lengths are 2.46 Å. There are two inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a 2-coordinate geometry to two equivalent K1+ and one Br1- atom. The Br–Br bond length is 2.48 Å. In the second Br1- site, Br1- is bonded in a distorted water-like geometry to three equivalent K1+ and one Pt4+ atom.
