[2,2′-(2,6,9,13-Tetra­azatetra­decane-1,14-di­yl)diphenolato]iron(III) iodide

The title Fe(III) complex, [Fe(C(22)H(32)N(4)O(2))]I, contains a six-coordinate FeN(4)O(2) cation in which the ligand is a reduced Schiff base resulting from the NaBH(4) 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-FeN(4)O(2) conformation for the phenolic O-atom donors, which contrasts with the trans conformation adopted by the analogous ClO(4) (−) 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.
