Triethylamine tris(hydrogen fluoride), a versatile fluorinating agent , solidifies at −27 °C forming pairs of hydrogen‐bonded Et 3 NH + and H 2 F 3 − ions. Six further low‐melting ionic amine–HF adducts have also been identified and their structures determined. The H n −1 F n − ions with n here taking values between 3 and 7 are classified along with those observed in other crystals.
