Phosphine has a trigonal pyramidal structure. Phosphines are compounds that include PH3 and the organophosphines, which are derived from PH3 by substituting one or more hydrogen atoms with organic groups. [4] They have the general formula PH3−nRn. Phosphanes are saturated phosphorus hydrides of the … See more Phosphine (IUPAC name: phosphane) is a colorless, flammable, highly toxic compound with the chemical formula PH3, classed as a pnictogen hydride.
