Materials Data on Cs2Pt3S4 by Materials Project

Cs2Pt3S4 crystallizes in the orthorhombic Fmmm space group. The structure is three-dimensional. Cs1+ is bonded in a 8-coordinate geometry to eight equivalent S2- atoms. There are a spread of Cs–S bond distances ranging from 3.75–3.94 Å. There are two inequivalent Pt2+ sites. In the first Pt2+ site, Pt2+ is bonded in a square co-planar geometry to four equivalent S2- atoms. All Pt–S bond lengths are 2.38 Å. In the second Pt2+ site, Pt2+ is bonded in a square co-planar geometry to four equivalent S2- atoms. All Pt–S bond lengths are 2.37 Å. S2- is bonded in a 7-coordinate geometry to four equivalent Cs1+ and three Pt2+ atoms.
