Materials Data on K3As(PSe3)3 by Materials Project
Abstract
K3As(PSe3)3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 9-coordinate geometry to nine Se+1.89- atoms. There are a spread of K–Se bond distances ranging from 3.46–4.00 Å. In the second K1+ site, K1+ is bonded in a 9-coordinate geometry to nine Se+1.89- atoms. There are a spread of K–Se bond distances ranging from 3.42–4.05 Å. In the third K1+ site, K1+ is bonded in a 8-coordinate geometry to one As1- and seven Se+1.89- atoms. The K–As bond length is 3.51 Å. There are a spread of K–Se bond distances ranging from 3.34–3.92 Å. As1- is bonded in a distorted trigonal pyramidal geometry to one K1+ and three Se+1.89- atoms. There are a spread of As–Se bond distances ranging from 2.44–2.47 Å. There are three inequivalent P5+ sites. In the first P5+ site, P5+ is bonded in a trigonal non-coplanar geometry to three Se+1.89- atoms. There are a spread of P–Se bond distances ranging from 2.16–2.29 Å. In the second P5+ site, P5+ is bonded in a trigonal non-coplanar geometry to three Se+1.89- atoms. There are a spread of P–Se bond distancesmore »
