The electron impact mass spectral fragmentation of five newly synthesized Ni(II) and Pd(II) complexes of diphenylphosphinoacetone (HL), i.e. trans ‐[ NiCl 2 (HL) 2 ] and trans ‐[PdCl 2 (HL) 2 ] and their enolates cis ‐[NiL 2 ] and cis ‐[PdL 2 ] and the bis‐enolate of 3‐diphenylphosphinobutan‐2‐one (HLMe), trans ‐[Ni(LMe) 2 ], is discussed. The proposed fragmentation mechanisms and the ion structures were confirmed by high‐resolution data for three of the compounds and by Ni and Pd isotope abundances. The results obtained reveal that a mass spectral differentiation is useful in the identification of these types of complexes. Especially with phosphinoenolate bis‐chelates molecular ion peaks are observed.
