Materials Data on La2SiS5 by Materials Project
Abstract
La2SiS5 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of La–S bond distances ranging from 2.86–3.13 Å. In the second La3+ site, La3+ is bonded in a 9-coordinate geometry to nine S2- atoms. There are a spread of La–S bond distances ranging from 2.92–3.40 Å. Si4+ is bonded in a tetrahedral geometry to four S2- atoms. There are a spread of Si–S bond distances ranging from 2.12–2.16 Å. There are five inequivalent S2- sites. In the first S2- site, S2- is bonded in a 1-coordinate geometry to three La3+ and one Si4+ atom. In the second S2- site, S2- is bonded to four La3+ atoms to form a mixture of distorted edge and corner-sharing SLa4 trigonal pyramids. In the third S2- site, S2- is bonded in a 1-coordinate geometry to four La3+ and one Si4+ atom. In the fourth S2- site, S2- is bonded in a 4-coordinate geometry to three La3+ and one Si4+ atom. In the fifth S2- site, S2- is bonded in a 4-coordinate geometry to three La3+ andmore »
