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

Abstract

Sulfur, so good: Crystallization of phosphorus polysulfides catena-P2S7 is enhanced by catalytic amounts of anhydrous FeCl3 (see scheme, P blue, S yellow). The formation of polysulfide bridges is observed which is typical for vulcanization reactions.
