The title FeIII complex, [Fe(C22H32N4O2)]I, contains a six-coordinate FeN4O2 cation in which the ligand is a reduced Schiff base resulting from the NaBH4 reduction of the condensation product between salicylaldehyde and 1,5,8,12-tetra­azadodecane. In spite of the increased flexibility of the saturated backbone of the ligand compared to the Schiff base from which it was synthesized, the complex adopts a cis-FeN4O2 conformation for the phenolic O-atom donors, which contrasts with the trans conformation adopted by the analogous ClO4 salt [Yisgedu et al. (2009). J. Chem. Crystallogr. 39, 315–319]. In addition to extensive N—H...I hydrogen bonding between the amine H atoms and the anion there is a weak C—H...I inter­action.
