(5-Fluoro-4′-methyl­biphenyl-3-yl)(2,4,6-tri­methyl­phen­yl)iodo­nium tri­fluoro­methane­sulfonate

In the title mol­ecular salt, C(22)H(21)FI(+)·CF(3)SO(3) (−), 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⋯π inter­actions present: together with the I⋯O bonds, these result in a three-dimensional network.
