In the first Cs1+ site, Cs1+ is bonded in a 9-coordinate geometry to nine S2- atoms. There are a spread of Cs–S bond distances ranging from 3.56–3.95 Å. In the second Cs1+ site, Cs1+ is bonded in a 9-coordinate geometry to nine S2- atoms. There are a spread of Cs–S bond distances ranging from 3.53–4.13 Å. In the third Cs1+ site, Cs1+ is bonded in a 11-coordinate geometry to eleven S2- atoms. There are a spread of Cs–S bond distances ranging from 3.51–4.19 Å. Sm3+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Sm–S bond distances ranging from 2.88–3.24 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded in a tetrahedral geometry to four S2- atoms. There are a spread of P–S bond distances ranging from 2.02–2.08 Å. In the second P5+ site, P5+ is bonded in a tetrahedral geometry to four S2- atoms. There are a spread of P–S bond distances ranging from 2.05–2.07 Å. There are eight inequivalent S2- sites.
