Abstract

Electron capture to monoanionic metal complexes in high-energy collisions with sodium vapor is shown to occur with the formation of dianions. In this way, we prepared the small dianions Cr(SCN)₄^2-, Fe(CN)₄^2-, Pt(NO₂)₂^2-, and Pt(C₂O₄)₂^2- in the gas phase. The Cr(SCN)₄^2- dianion Coulomb explodes into Cr(SCN)₃^- and SCN^- with a release of kinetic energy (3.2 ± 0.4 eV) into translational energy of the fragments. The scheme provides a way to study charge dissociation reactions of molecular dianions that are too short-lived to survive extraction from the ion source.
