Summary

  1. 1.

    A study has been made of the mass spectra of tricarbonyliron complexes of 1-sila-2,4-cyclohexadiene with various substituents on the silicon atom.

  2. 2.

    The main route of fragmentation of the tricarbonyliron complexes under electron impact is successive decarbonylation with subsequent elimination of an HR molecule with the participation of the iron atom.

  3. 3.

    Structures have been proposed for the ions C5H5SiRFe+, C5H5Si+, and C3H3Si+. In the decomposing C5H5SiRFe+ ions, interaction of the iron atom with the silicon atom takes place, whereas the nondecomposing ions probably have the structure of coordinated silabenzene. A pyramidal structure of the nido-cluster type is ascribed to the C5H5Si+ and C3H3Si+ ions.
