Abstract: The crystal structures of [(Z)-2-methylbut-1-en-1-yl][4-(trifluoromethyl)phenyl]iodonium trifluoromethanesulfonate, C₁₂H₁₃F₃I⁺·CF₃O₃S^-, (I), (3,5-dichlorophenyl)[(Z)-2-methylbut-1-en-1-yl]iodonium trifluoromethanesulfonate, C₁₁H₁₂Cl₂I⁺·CF₃O₃S^-, (II), and bis{[3,5-bis(trifluoromethyl)phenyl][(Z)-2-methylbut-1-en-1-yl]iodonium} bis(trifluoromethanesulfonate) dichloromethane solvate, 2C₁₃H₁₂F₆I⁺·2CF₃O₃S^-·CH₂Cl₂, (III), are described. Neither simple acyclic [beta] , [beta] -dialkyl-substituted alkenyl(aryl)idonium salts nor a series containing electron-deficient aryl rings have been described prior to this work. Compounds (I)-(III) were found to have distorted square-planar geometries, with each I atom interacting with two trifluoromethanesulfonate counter-ions.

Formula: C₁₂H₁₃F₃I⁺·CF₃O₃S^-, C₁₁H₁₂Cl₂I⁺·CF₃O₃S^- and 2C₁₃H₁₂F₆I⁺·2CF₃O₃S^-·CH₂Cl₂
