The preparation of the α-iodo-substituted tripods within the series of tris(2-pyridylmethyl)amine ligands, and the characterization of the corresponding I1-3TPAFeCl2 complexes

► The α-iodo substituted tripods I1TPA, I2TPA and I3TPA have been prepared. ► The crystal structures of the high-spin complexes I1TPAFeCl2 and I2TPAFeCl2 are reported. ► I1TPAFeCl2 exhibits the expected distorted octahedral geometry. ► Intramolecular π-stacking of two adjacent molecules occurs in solid state in I2TPAFeCl2.
