Materials Data on K2PtS6 by Materials Project
K2PtS6 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. K1+ is bonded in a 6-coordinate geometry to six S+0.67- atoms. There are a spread of K–S bond distances ranging from 3.22–3.44 Å. Pt2+ is bonded in a distorted hexagonal planar geometry to six S+0.67- atoms. All Pt–S bond lengths are 2.39 Å. There are two inequivalent S+0.67- sites. In the first S+0.67- site, S+0.67- is bonded in a 3-coordinate geometry to two equivalent K1+ and one Pt2+ atom. In the second S+0.67- site, S+0.67- is bonded in a 4-coordinate geometry to two equivalent K1+, one Pt2+, and one S+0.67- atom. The S–S bond length is 2.11 Å.
