Phosphorus triselenide

Phosphorus Triselenide or Phosphorous Selenide, P2Se3.— This compound may be obtained by heating together phosphorus and selenium in the requisite atomic proportions. The reaction is accompanied by a great evolution of heat. The product is a ruby-red solid, which is combustible on heating. It is insoluble in carbon disulphide. With metal selenides it forms double selenides of the typeP2Se3.2MSe.2... [Pg.342]
