The negative ion mass spectra of some divalent metal complexes, ML 2 , have been measured, where MCo, Ni and Cu, and LH = salicylaldehyde or 2‐hydroxy‐1‐naphthylaldehyde. All compounds yield intense molecular anions. The mass spectra of these compounds suggest that consecutive and competitive eliminations of CO and H 2 CO, and various types of hydrogen migrations are involved in the fragmentation of the molecular anions. The mechanism of the fragmentation process and metastable peaks observed are also discussed.
