Phosphine \Phos"phine\, n. (Chem.) A colorless gas, PH3, analogous to ammonia, and having a disagreeable odor resembling that of garlic. Called also hydrogen phosphide, and formerly, phosphureted hydrogen.
Note: It is the most important compound of phosphorus and hydrogen, and is produced by the action of caustic potash on phosphorus. It is spontaneously inflammable, owing to impurities, and in burning produces peculiar vortical rings of smoke.

Wikipedia
Phosphine ( IUPAC name: phosphane) is the compound with the chemical formula PH. It is a colorless, flammable, toxic gas and pnictogen hydride. Pure phosphine is odorless, but technical grade samples have a highly unpleasant odor like garlic or rotting fish, due to the presence of substituted phosphine and diphosphane (PH). With traces of PH present, PH is spontaneously flammable in air, burning with a luminous flame. Phosphines are also a group of organophosphorus compounds with the formula RP (R = organic derivative). Organophosphines are important in catalysts where they complex to various metal ions; complexes derived from a chiral phosphine can catalyze reactions to give chiral, enantioenriched products.
