(2-Methoxy-5-methylphenyl)(4-methoxy-2-methylphenyl)iodonium trifluoroacetate

The asymmetric unit of the title compound, C16H18IO2 +· CF3CO2 -, comprises an iodo-nium cation and a trifluoro-acetate anion, in which the F atoms are disordered over two postions of equal occupancy. The benzene rings are inclined at 87.76 (5)° to one another. Extremely short inter-molecular I⋯O contacts [2.807 (9) and 3.019 (13) Å] occur, due to strong electrostatic inter-actions between the I atom and two adjacent trifluoro-acetate counter-ions. © International Union of Crystallography 2007.
