Structure and properties of even-electron anionic species formed by bis(2-ethylhexyl)sulfosuccinate (AOT) and divalentmetal ions(MII) with stoichiometry [AOTMIICl2]– have been investigated by using electrospray ionization and different mass spectrometrytechniques, such as high resolution, accurate mass measurements, collision-induced dissociation (CID) multiple-stage massspectrometry.Owing to CID, eliminations of neutrals,mainly consisting in hydrochloric acid, 2-ethyl-1-hexene and 2-ethylhexanol,and an unexpected loss of an alkyl radical have been observed. The radical anions [C4HO6SMIICl]–• so produced have beencharacterized by MS3 experiments. Density functional theory calculations have been carried out for investigating structure andstability of the ionic species formed in the decomposition pathways.
