The structure of an Fe(III) complex of reduced Schiff base is reported. The title compound, C21H30ClFeN4O6 (I), crystallizes in the monoclinic space group P21/n with cell constants: a = 9.988(2) A, b = 20.430(5) A, c = 11.415(3) A, β = 105.480(4)°. It contains a six-coordinate FeN4O 4 cation where the ligand is a reduced Schiff base resulting from the NaBH4 reduction of the condensation product between salicylaldehyde and 1,4,8,11-tetraazaundecane. Due to the increased flexibility of the saturated backbone of the ligand compared to the Schiff base from which it was synthesized, the complex adopts a trans-FeN4O2 conformation. There is extensive hydrogen bonding between the amine H atoms and the anion O atoms. Springer Science+Business Media, LLC 2008.
