Diphosphorus pentasulphide

The white phosphorus/sulphur mixture either combusts or detonates when it is heated. It forms diphosphorus pentasulphide. Red phosphorus reacts with more difficulty there is a need for an ignition flame and as a result of which the mixture combusts violently. This reaction is thought to lead to tetraphosphorus trisulphide.
