Abstract

The mass spectral behavior of a number of organometallic complexes containing the Group 10 metals Ni, Pd, and Pt, together with various thiolate ligands were studied. For Pd, two main types of complexes, differing by the substituents on the phosphorus atom were studied. Types I and II were substituted with bis(diphenylphosphino)ferrocene and bis(diisopropylphosphino) ferrocene ligands, respectively. The Ni complexes, except for one, and the Pd Type I complexes had no molecular radical cations (M ⁺) in their EI spectra. On the other hand, all the Pt complexes showed intense M ⁺ ions in their EI spectra indicating that these complexes were more stable as radical cations than those of Ni and Pd. The FAB and MALDI spectra of all the complexes displayed intense quasi-molecular ions (MH ⁺) and the fragmentations in both modes were similar. The MALDI spectra of several complexes displayed only M ⁺ ions while one gave evidence of both MH ⁺ and M ⁺ ions. Several Pd Type II complexes yielded intense M ⁺ in their EI spectra.
