Mass spectra of N,N′‐bis(salicylidene)ethylenediamine (I) and its nickel complex (III) and of N,N′‐bis(salicylidene)isobutylenediamine (II) and its nickel, cobalt, copper and palladium complexes (IV to VII) have been investigated. The metal chelates' spectra are marked by intense molecular ions and a general paucity of metal‐free ions, though chelates of the more readily reducible metals (Cu, Pd) show more ligand ions. In general, the principal fragmentations are the same for both chelates and ligands, but some specific fragmentations are found for individual chelates.
