Title: Materials Data on KEuPSe4 by Materials Project

Abstract

KEuPSe4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. K1+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of K–Se bond distances ranging from 3.48–3.66 Å. Eu2+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of Eu–Se bond distances ranging from 3.14–3.66 Å. P5+ is bonded in a tetrahedral geometry to four Se2- atoms. There are one shorter (2.23 Å) and three longer (2.25 Å) P–Se bond lengths. There are three inequivalent Se2- sites. In the first Se2- site, Se2- is bonded to three equivalent K1+, one Eu2+, and one P5+ atom to form distorted corner-sharing SeK3EuP trigonal bipyramids. In the second Se2- site, Se2- is bonded in a 5-coordinate geometry to two equivalent K1+, two equivalent Eu2+, and one P5+ atom. In the third Se2- site, Se2- is bonded in a 5-coordinate geometry to one K1+, three equivalent Eu2+, and one P5+ atom.
