Materials Data on CsPSe6 by Materials Project
Abstract
CsPSe6 crystallizes in the tetragonal P-42_1c space group. The structure is three-dimensional. there are five inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded to twelve Se1- atoms to form CsSe12 cuboctahedra that share edges with four equivalent PSe4 tetrahedra. There are a spread of Cs–Se bond distances ranging from 3.79–4.04 Å. In the second Cs1+ site, Cs1+ is bonded in a body-centered cubic geometry to eight Se1- atoms. There are four shorter (3.82 Å) and four longer (3.91 Å) Cs–Se bond lengths. In the third Cs1+ site, Cs1+ is bonded in a body-centered cubic geometry to eight Se1- atoms. There are four shorter (3.82 Å) and four longer (3.91 Å) Cs–Se bond lengths. In the fourth Cs1+ site, Cs1+ is bonded in a 12-coordinate geometry to fourteen Se1- atoms. There are a spread of Cs–Se bond distances ranging from 3.96–4.28 Å. In the fifth Cs1+ site, Cs1+ is bonded in a 12-coordinate geometry to fourteen Se1- atoms. There are a spread of Cs–Se bond distances ranging from 3.96–4.28 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four Se1- atoms to form PSe4 tetrahedra that share an edgeedge with onemore »
