Phosphorus trifluoride (formula P F 3), is a colorless and odorless gas.It is highly toxic and reacts slowly with water. Its main use is as a ligand in metal complexes.As a ligand, it parallels carbon monoxide in metal carbonyls, [1] and indeed its toxicity is due to its binding with the iron in blood hemoglobin in a similar way to carbon monoxide.

Many metals form trifluorides, such as iron, the rare-earth elements, and the metals in the groups 3, 13 and 15 of the periodic table. Most metal trifluorides are poorly soluble in water except ferric fluoride and indium(III) fluoride , but several are soluble in other solvents.

Phosphorus fluoride may refer to any of the following: Phosphorus trifluoride, PF 3; Phosphorus pentafluoride, PF 5; Diphosphorus tetrafluoride, [1] P 2 F 4; See phosphorus halides for a complete list of phosphorus halides.
In early work, phosphine ligands were thought to utilize 3d orbitals to form M-P pi-bonding, but it is now accepted that d-orbitals on phosphorus are not involved in bonding. [9] The energy of the σ* orbitals is lower for phosphines with electronegative substituents , and for this reason phosphorus trifluoride is a particularly good π-acceptor.
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
