Abstract

A trinucleating cyclophane bearing three β-diketimine arms, and the corresponding iron(II) and manganese(II) complexes have been synthesized and characterized. The three metal ions are oriented towards the internal void space, and are coordinated by a N₂Br₂ donor set, in which a unique combination of μ³, μ, and terminal coordination modes are observed for the halide donors.
