    Notes: Abstract According to the protonation of [PPh4]2[Ru6C(CO)16] (1b) withp-toluene-sulfonic acid, a hydrido ruthenium cluster [PPh4][Ru6C(CO)16H] (3b) was obtained in 53% yield, which readily decomposed in protic solvents even at −20°C to yield1b, Ru6C(CO)16H2, and Ru5C(CO)15. Cluster3b was characterized by single-crystal X-ray analysis. The six metal atoms are arranged in the form of an octahedron with the carbido ligand located in the center. There are 13 terminal carbonyl, three bridging carbonyl, and a bridging hydrido ligands.

    Mass spectra of π-cyclopentadienyl-diene cobalt complexes (1970)
    Chichester : Wiley-Blackwell
    Biological Mass Spectrometry 3 (1970), S. 23-29 
    Details
    ISSN: 0030-493X
    Keywords: Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: Many reports on the mass spectra of organotransition-metal complexes have appeared in recent years,1 whilst there have only been a few reports on the mass spectra of transition metal olefin complexes, some metal carbonyl olefin complexes234 and π-cyclooctenyl-π-cyclooctadienyl cobalt.5 Recently fragmentation paths of π-cyclopentadienyl-cyclooctadiene rhodium were elucidated by King.6 The present authors found metastable ions in the mass spectra of π-cyclopentadienyl-diene cobalt complexes as well as in the mass spectra of π-cyclopentadienyl-diene rhodium complexes.7.In the present paper the authors wish to report the mass spectra of several π-cyclopentadienyl diene cobalt complexes.
