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 I...O 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-H...F and C-H...[pi] inter­actions present: together with the I...O bonds, these result in a three-dimensional network.
