[2,2'-(2,6,9,13-Tetra-azatetra-decane-1,14-di-yl)diphenolato]iron(III) iodide.

ABSTRACT: 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-tetra-azadodecane. 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 inter-action.
