Materials Data on Cs2Pt3Se4 by Materials Project
Cs2Pt3Se4 crystallizes in the orthorhombic Fmmm space group. The structure is three-dimensional. Cs1+ is bonded in a 8-coordinate geometry to eight equivalent Se2- atoms. There are a spread of Cs–Se bond distances ranging from 3.87–4.08 Å. There are two inequivalent Pt2+ sites. In the first Pt2+ site, Pt2+ is bonded in a square co-planar geometry to four equivalent Se2- atoms. All Pt–Se bond lengths are 2.50 Å. In the second Pt2+ site, Pt2+ is bonded in a square co-planar geometry to four equivalent Se2- atoms. All Pt–Se bond lengths are 2.49 Å. Se2- is bonded in a 7-coordinate geometry to four equivalent Cs1+ and three Pt2+ atoms.
