Abstract

The crystal structures of the self-assembled metallapentacycles [{Fe ₅(bptz)₅(CH₃CN)₁₀} ⊂ 2SbF ₆][SbF₆]₈ (1) and [{Fe₅(bmtz) ₅(CH₃CN)₁₀} ⊂ SbF₆][SbF ₆]₉ (2) with the π-acidic ligands bptz (3,6-bis(2-pyridyl)-1,2,4,5-tetrazine) and bmtz (3,6-bis(2-pyrimidyl)-1,2,4,5- tetrazine), respectively, revealed cationic pentagons templated by [SbF ₆]^- ions. The short anion-π contacts established between the anions and the tetrazine rings play an important role in the stability of the pentagons.
