Chemical compound

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]
