Under electron impact malonaldehydedianil and its bis Co(II), Ni(II) and Zn(II) complexes produce a stable molecular ion. The Cu(II) complex appears to decompose prior to ionization. The free dianil molecular ion fragments by expulsion of the azomethine proton or by fission of C‐N bonds. The molecular ions of the metal complexes usually expel a complete ligand before undergoing demetallation.
