Materials Data on La6Mg(SiS7)2 by Materials Project
Abstract
La6MgSi2S14 crystallizes in the trigonal P3 space group. The structure is three-dimensional. Mg2+ is bonded in an octahedral geometry to six S2- atoms. There are three shorter (2.62 Å) and three longer (2.63 Å) Mg–S bond lengths. 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 2.87–3.17 Å. In the second 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 2.89–3.12 Å. There are two inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded in a tetrahedral geometry to four S2- atoms. There are one shorter (2.10 Å) and three longer (2.15 Å) Si–S bond lengths. In the second Si4+ site, Si4+ is bonded in a tetrahedral geometry to four S2- atoms. There are one shorter (2.11 Å) and three longer (2.15 Å) Si–S bond lengths. There are six inequivalent S2- sites. In the first S2- site, S2- is bonded in a distorted tetrahedral geometry to three equivalent La3+ and one Si4+ atom. In the second S2- site, S2- is bondedmore »
