Dimethylphenylsulfonium trifluoromethanesulfonate and methyldiphenylsulfonium trifluoromethanesulfonate.

The bonding geometry of sulfur in the cations of the title compounds, C(8)H(11)S(+).CF(3)SO(3)(-) and C(13)H(13)S(+).CF(3)SO(3)(-), respectively, is similar and is independent of the ratio of the Me/Ph substituents. As expected, in both cations, the S-Ph bonds are somewhat shorter than the S-Me bonds. In both crystal structures, the interaction between cations and anions is similar.
