Phosphorus trifluorodichloride is a chemical compound with the chemical formula PF₃Cl₂. The covalent molecule trigonal bipyramidal molecular geometry. The central phosphorus atom has sp³d hybridization, and the molecule has an asymmetric charge distribution. It appears as a colorless gas with a disagreeable odor, and it turns into a liquid at -8 °C.

Phosphorus trifluorodichloride is formed by mixing phosphorus trifluoride with chlorine PF₃ + Cl₂ → PF₃Cl₂^[1]

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.^[1]
