Abstract

The first crystallographic and electron density distribution analyses of a thioaroyl cation unveil its true structural perspective; this chemical species can be mainly expressed as the combination of the thioketene form (II) and sulfonium form (III) with a C [triple bond, length as m-dash] S⁺ triple bond character.
