    • note
    • Such a valency assessment has no consequences for the magnetism of a "typical" organometallic center, with S = 0 even-electron metal ions. However, in principle it has experimentally observable consequences for the magnetic properties of a metal cluster comprised of spin-coupled high-spin, open-shell Fe(II/III) ions: the two electrons provided by the cofactor to the C-Fe σ-bonds of the ferracyclopropane no longer participate in the cluster spin system, and the consequence to the ion would be the same (magnetically) as if complex formation had driven it to intermediate spin.
