摘要

The salt [K([18]crown-6){Cp*Fe(η~4-C_4py_4)}] (K1, py = 2-pyridyl, Cp* = C_5Me_5) is accessible by the reaction of an iron(0) naphthalene precursor and bis(2-pyridyl)acetylene. Cyclic voltammetry and preparative investigations demonstrate the electron-rich nature of K1, which is reversibly oxidized to neutral [Cp*Fe(η~4-C_4py_4)] (1) at a low potential. The first coordination studies with iron(II) and zinc(II) chloride show that all four 2-pyridyl units may be employed for metal coordination.
