Phosphanides are chemicals containing the [PH2]− anion. This is also known as the phosphino anion or phosphido ligand. The IUPAC name can also be dihydridophosphate(1−).[1]
It can occur as a group phosphanyl -PH2 in organic compounds or ligand called phosphanido, or dihydridophosphato(1−). A related substance has PH2−. Phosphinidene (PH) has phosphorus in a −1 oxidation state.[2]
As a ligand PH2 can either bond to one atom or be in a μ2-bridged ligand across two metal atoms.[3] With transition metals and actinides, bridging is likely unless the metal atom is mostly enclosed in a ligand.
In phosphanides, phosphorus is in the −3 oxidation state. When phosphanide is oxidised, the first step is phosphinite ([H2PO]−). Further oxidation yields phosphonite ([HPO2]2−)and phosphite ([PO3]3−).[4]
The study of phosphine derivatives is unpopular, because they are unstable, poisonous and malodorous.[5]
