Materials Data on P4S7 by Materials Project
P4S7 is High Pressure (4-7GPa) Tellurium structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four P4S7 clusters. there are four inequivalent P+3.50+ sites. In the first P+3.50+ site, P+3.50+ is bonded in a water-like geometry to two S2- atoms. Both P–S bond lengths are 2.12 Å. In the second P+3.50+ site, P+3.50+ is bonded in a water-like geometry to two S2- atoms. Both P–S bond lengths are 2.12 Å. In the third P+3.50+ site, P+3.50+ is bonded to four S2- atoms to form corner-sharing PS4 tetrahedra. There are a spread of P–S bond distances ranging from 1.93–2.14 Å. In the fourth P+3.50+ site, P+3.50+ is bonded to four S2- atoms to form corner-sharing PS4 tetrahedra. There are a spread of P–S bond distances ranging from 1.93–2.13 Å. There are seven inequivalent S2- sites. In the first S2- site, S2- is bonded in a water-like geometry to two P+3.50+ atoms. In the second S2- site, S2- is bonded in a water-like geometry to two P+3.50+ atoms. In the third S2- site, S2- is bonded in a water-like geometry to two P+3.50+ atoms. In the fourth S2- site, S2- is bonded in a water-like geometry to two P+3.50+ atoms. In the fifth S2- site, S2- is bonded in a single-bond geometry to one P+3.50+ atom. In the sixth S2- site, S2- is bonded in a single-bond geometry to one P+3.50+ atom. In the seventh S2- site, S2- is bonded in a water-like geometry to two P+3.50+ atoms.
