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.

Phosphorus trifluorodichloride is formed by mixing phosphorus trifluoride with chlorine PF 3 + Cl 2 → PF 3 Cl 2 [2] The P-F bond length is 1.546 Å for equatorial position and 1.593 for the axial position and the P-Cl bond length is 2.004 Å. The chlorine atoms are in equatorial positions in the molecule. [2]
Phosphorus(II) halides may be prepared by passing an electric discharge through a mixture of the trihalide vapour and hydrogen gas. [ citation needed ] The relatively stable P 2 I 4 is known to have a trans , bent configuration similar to hydrazine and finds some uses in organic syntheses, the others are of purely academic interest at the ...
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 ...
from phosphorus trifluoride PF 3 and ... with four covalent bonds and one ionic bond ... phosphorus compounds. In A, the N–P bond is 1.980 Å long and the C–P is ...
