The synthesis, structure and reactivity of room-temperature-stable [Cp(C6F5)5]+[Sb3F16]− is presented. Coordination of the cyclopentadienyl cation by [Sb3F16]− or C6F6 stabilizes the antiaromatic singlet state in the solid state. Calculated hydride and fluoride ion affinities of the [Cp(C6F5)5]+ cation are higher than those of the tritylium cation [C(C6F5)3]+.
