Materials Data on CsK2Pt by Materials Project

Abstract

CsK2Pt crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Cs is bonded in a distorted square co-planar geometry to four Pt atoms. All Cs–Pt bond lengths are 3.99 Å. K is bonded in a bent 120 degrees geometry to two equivalent Pt atoms. Both K–Pt bond lengths are 3.31 Å. There are two inequivalent Pt sites. In the first Pt site, Pt is bonded in a distorted body-centered cubic geometry to four equivalent Cs and four equivalent K atoms. All Pt–K bond lengths are 3.31 Å. In the second Pt site, Pt is bonded in a 8-coordinate geometry to four equivalent Cs and four equivalent K atoms.
