WebApr 3, 2024 · Phosphines are two electron donors that engage a lone pair for binding to metals. These are thus considered as good σ−donors and poor π−acceptors and they belong to the same class with the aryl, dialkylamino and alkoxo ligands. In fact they are more π−acidic than pure σ−donor ligands like NH 3 and, more interestingly so, their π− ... WebPhosphine is the common name for phosphorus hydride (PH 3), also known by the IUPAC name phosphane and, occasionally, phosphamine.It is a colorless, flammable gas with a boiling point of −88 °C at standard pressure.Pure phosphine is odorless, but technical grade phosphine has a highly unpleasant odor like garlic or rotting fish, due to the presence of … i power vs phresh filter
