    • A search of the Cambridge Crystallographic Structure Database revealed that the terminal Si-Cl bond in 2 is the longest such bond in crystallographically characterized transition metal complexes. The median bond lengthfor all crystallographically characterized Si-Cl bonds is 2.063 Å.

    • 21b is the only compound with a longer Si-O bond (1.926 Å). The median bond lenght for all crystallographically characterized bonds between four-coordinate silicon and oxygen is 1.635 Å.

    • note
    • 29Si chemical shift of three-coordinate silicenium ions has been shown by computational methods to be sensitive to nucleophiles as weak as argon. By analogy, a similar sensitivity to very weakly nucleophilic species such as triflate is expected for silylene complexes.

    • note
    • The disorder in the Cp* ring and the magnitude of the associated uncertainty preclude a meaningful comparison of the length of the Os-Si bond in 6 to the analogous bond in 7. It is, however, significantly shorter than the Os-Si bond 2.334(2) Å in 5.
