Phosphorus Compounds with the VI B Group Elements

Abstract

The preparation and the properties of phosphorus sulfides and selenides are reviewed. The exact number of phosphorus sulfides and selenides has been determined from the phase diagram. Phosphorus does not react with tellurium. The ternary diagram P—S—Se shows no P—S—Se compounds. The domains of P—S and P—Se glasses has been also determined. IR and mass spectrometry show that phosphorus sulfides and selenides have a tetrahedral arrangement of P atoms close to that of white phosphorus. © 1976, Walter de Gruyter. All rights reserved.
