Abstract: In the title molecular salt, C22H21FI+·CF3SO3-, the dihedral angle between the rings of the biphenyl group is 65.6 (1)°. The ring of the mesitylene group is inclined to the fluorobenzene ring at an angle of 86.1 (3)° and the C-I-C bond angle is 97.0 (2)°. In the crystal, extremely short IO contacts of 2.862 (5) and 2.932 (5) Å occur, due to the strong electrostatic interactions between the I atom and two adjacent trifluoromethanesulfonate counter-ions. There are also C-HF and C-H interactions present: together with the IO bonds, these result in a three-dimensional network.
