Abstract:
In the title mol-ecular 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 fluoro-benzene 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 inter-actions between the I atom and two adjacent tri-fluoro-methane-sulfonate counter-ions. There are also C-H⋯F and C-H⋯π inter-actions present: together with the I⋯O bonds, these result in a three-dimensional network.
