Additional notes
DefinitionChEBI: The simplest of the diphosphanes, consisting of two covelently linked phosphorus atoms each carrying two hydrogens.
DefinitionA yellow liquid that can be condensed out from phosphine in a freezing mixture. It ignites spontaneously in air.
Definitiondiphosphine: A yellowliquid, P2H4, which is spontaneouslyflammable in air. It isobtained by hydrolysis of calciumphosphide. Many of the references tothe spontaneous flammability ofphosphine (PH3) are in fact due totraces ofP2H4 as impurities.
