Materials Data on KEuPSe4 by Materials Project
KEuPSe4 crystallizes in the monoclinic P2_1/m 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 3.43–3.70 Å. Eu2+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of Eu–Se bond distances ranging from 3.10–3.64 Å. P5+ is bonded in a tetrahedral geometry to four Se2- atoms. There are a spread of P–Se bond distances ranging from 2.22–2.24 Å. 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 a mixture of distorted edge and corner-sharing SeK3EuP trigonal bipyramids. In the second Se2- site, Se2- is bonded in a 5-coordinate geometry to one K1+, three equivalent Eu2+, and one P5+ atom. In the third Se2- site, Se2- is bonded in a 5-coordinate geometry to two equivalent K1+, two equivalent Eu2+, and one P5+ atom.
