Phosphine - Wikipedia

Phosphine (IUPAC name: phosphane) is a colourless, flammable, very toxic gas compound with the chemical formula PH 3, classed as a pnictogen hydride. Pure phosphine is odourless, but technical grade samples have a highly unpleasant odour like rotting fish, due to the presence of substituted phosphine and diphosphane (P 2 H 4). With traces of P 2 H 4 present, PH 3 is spontaneously flammable in ...
