The mass spectrometric behaviour of mono‐, di‐ and trimethylenebis(diphenylphosphine)‐Pt(II)‐ cis ‐dichloro and ‐dicyano drivatives has been studied with the aid of two different ionization techniques (electron ionization and fast‐atom bombardment) and metastable ion studies, with the aim of finding the most suitable mass spectrometric technique for determining the real monomeric or dimeric structure of such compounds. Electron ionization mass spectrometry led to the best results in terms of molecular ion identification and production of fragment ions well‐related to the original structure. On the contrary, fast‐atom bombardment led to the formation of dimeric species for Pt{1,2‐bis(diphenylphosphino)methane}Cl 2 and Pt{1,2‐bis(diphenylphosphino)methane}(CN) 2 due to the high reactivity of the monomeric molecules in the condensed phase.
