Materials Data on Cs2Sb2Pt by Materials Project

Abstract

Cs2PtSb2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a distorted L-shaped geometry to two equivalent Sb atoms. Both Cs–Sb bond lengths are 3.84 Å. In the second Cs1+ site, Cs1+ is bonded in a 6-coordinate geometry to two equivalent Pt2- and two equivalent Sb atoms. Both Cs–Pt bond lengths are 3.47 Å. Both Cs–Sb bond lengths are 4.00 Å. Pt2- is bonded to two equivalent Cs1+ and four equivalent Sb atoms to form face-sharing PtCs2Sb4 octahedra. All Pt–Sb bond lengths are 2.69 Å. Sb is bonded in a 2-coordinate geometry to two Cs1+, two equivalent Pt2-, and one Sb atom. The Sb–Sb bond length is 2.84 Å.
