Double deprotonation of the diamine 1,1'-(tBuCH<sub>2</sub> NH)-ferrocene (1-H<sub>2</sub> ) by alkaline-earth (Ae) or Eu<sup>II</sup> metal reagents gave the complexes 1-Ae (Ae=Mg, Ca, Sr, Ba) and 1-Eu. 1-Mg crystallized as a monomer while the heavier complexes crystallized as dimers. The Fe⋅⋅⋅Mg distance in 1-Mg is too long for a bonding interaction, but short Fe⋅⋅⋅Ae distances in 1-Ca, 1-Sr, and 1-Ba clearly support intramolecular Fe⋅⋅⋅Ae bonding. Further evidence for interactions is provided ...[more]
