ChemInform Abstract: Rational Syntheses and Structural Characterization of Sulfur‐Rich Phosphorus Polysulfides: α‐P₂S₇ and β‐P₂S₇.

Abstract

The polysulfides α‐ and β‐P2S7 are synthesized by heating stoichiometric mixtures of P4S3 and sulfur in the presence of catalytic amounts of anhydrous FeCl3 as mineralizer (evacuated silica tube, 250 °C, 10 d).

Interface Stability of Argyrodite Li6PS5Cl toward LiCoO2, LiNi1/3Co1/3Mn1/3O2, and LiMn2O4 in Bulk All-Solid-State Batteries

“…For example, P 2 S 7 contains a three-sulfur S−S−S chain as well as the sulfur environments found in P 2 S 5 and was already described by other authors. 22 Therefore, sulfur can form polysulfides by oxidation of Li 6 PS 5 Cl, but so does phosphorus through S−...−S chains in P 2 S x species.…”

Fluorotrithiophosphate Abstraction from the Difluoropentathiodiphosphate Dianion: d8 and d6 Complexes of [η2-S3PF]2–

“…The most common monomer is the tetrahedral [PS 4 ] 3− anion (Figure 1A) with dimeric thiophosphates and thio analogues of pyrophosphate, such as [P 2 S 6 ] 2− , [P 2 S 6 ] 4− , [P 2 S 7 ] 4− or [P 2 S 9 ] 4− being relatively common as well (Figures 1B−E). 1,2 The presence of terminal S atoms in these structures suggests the possibility of forming bidentate ligands in transition-metal complexes. 3 Complexes with [PS 4 ] 3− , 4 [P 2 S 6 ] 2− , [P 2 S 6 ] 4− , 5−7 [P 2 S 7 ] 4− , 7−11 and [P 2 S 9 ] 4−11 ligands or combinations thereof 12−16 have been reported.…”

In Situ X-ray Diffraction Study of the Thermal Decomposition of Selenogallates Cs2[Ga2(Se2)2–xSe2+x] (x = 0, 1, 2)

“…4−16 Incorporation of such polychalcogenide units into the anionic structures leads to the formation of more complex, uncommon one-dimensional structures like CsGaQ 3 , 4,5 Cs 2 Ga 2 Q 5 , 6,7 CsAlTe 3 , 8 several perchalcogenoborates 9−11 and -antimonates, 12−15 or the neutral chains in P 2 S 7 . 16 The polychalcogenide units Q 2 2− or Q 3 2− in such compounds have a significant influence on the semiconducting properties of these substances. 17 We recently reported on our investigations of ternary thiogallates CsGaS 3 , 5 Cs 2 Ga 2 S 5 , 6 and CsGaS 2 .…”
