Materials Data on RbPSe6 by Materials Project

Abstract

RbPSe6 crystallizes in the orthorhombic Pca2_1 space group. The structure is three-dimensional. Rb1+ is bonded in a 12-coordinate geometry to twelve Se1- atoms. There are a spread of Rb–Se bond distances ranging from 3.57–4.22 Å. P5+ is bonded in a tetrahedral geometry to four Se1- atoms. There are a spread of P–Se bond distances ranging from 2.18–2.34 Å. There are six inequivalent Se1- sites. In the first Se1- site, Se1- is bonded in a distorted single-bond geometry to two equivalent Rb1+ and one P5+ atom. In the second Se1- site, Se1- is bonded in a distorted single-bond geometry to two equivalent Rb1+, one P5+, and one Se1- atom. The Se–Se bond length is 2.37 Å. In the third Se1- site, Se1- is bonded in a distorted trigonal non-coplanar geometry to two equivalent Rb1+ and two Se1- atoms. The Se–Se bond length is 2.45 Å. In the fourth Se1- site, Se1- is bonded in a 4-coordinate geometry to two equivalent Rb1+ and two Se1- atoms. The Se–Se bond length is 2.42 Å. In the fifth Se1- site, Se1- is bonded in a distorted single-bond geometry to one Rb1+, one P5+, and one Se1- atom. In the sixth Se1- site, Se1- is bonded in a distorted single-bond geometry to three equivalent Rb1+ and one P5+ atom.
