Materials Data on Rb4Ge(PS3)4 by Materials Project
Rb4Ge(PS3)4 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 10-coordinate geometry to ten S2- atoms. There are a spread of Rb–S bond distances ranging from 3.51–4.07 Å. In the second Rb1+ site, Rb1+ is bonded in a 9-coordinate geometry to nine S2- atoms. There are a spread of Rb–S bond distances ranging from 3.31–3.99 Å. Ge2+ is bonded in a tetrahedral geometry to four S2- atoms. There are two shorter (2.25 Å) and two longer (2.26 Å) Ge–S bond lengths. There are two inequivalent P+4.50+ sites. In the first P+4.50+ site, P+4.50+ is bonded in a trigonal non-coplanar geometry to three S2- atoms. There are a spread of P–S bond distances ranging from 1.97–2.17 Å. In the second P+4.50+ site, P+4.50+ is bonded in a trigonal non-coplanar geometry to three S2- atoms. There are two shorter (1.98 Å) and one longer (2.20 Å) P–S bond lengths. There are six inequivalent S2- sites. In the first S2- site, S2- is bonded in a distorted single-bond geometry to three equivalent Rb1+ and one P+4.50+ atom. In the second S2- site, S2- is bonded in a distorted single-bond geometry to four Rb1+ and one P+4.50+ atom. In the third S2- site, S2- is bonded in a 2-coordinate geometry to two Rb1+, one Ge2+, and one P+4.50+ atom. In the fourth S2- site, S2- is bonded in a 1-coordinate geometry to three Rb1+ and one P+4.50+ atom. In the fifth S2- site, S2- is bonded in a 1-coordinate geometry to four Rb1+ and one P+4.50+ atom. In the sixth S2- site, S2- is bonded in a 2-coordinate geometry to three equivalent Rb1+, one Ge2+, and one P+4.50+ atom.
