A summary of the mass spectra of metal dithiocarbamate complex salts (ML 2 and ML 3 ) is presented. Only divalent metal dithiocarbamate ions without an electronic configuration containing an inert s‐orbital electron pair exhibited both expulsion of a ligand radical (L) and the neutral even electron species (L–H) generated from the ligand via hydrogen transfer to the metal‐containing fragment ion. Divalent metal dithiocarbamate ions can be generated either by direct electron impact ionization of gas phase ML 2 molecules or ionization of ML 3 molecules followed by loss of a ligand radical. A highly stable sp 2 hybridized, gas phase ion of a monobidentate lead dithiocarbamate complex is proposed.
