The main molecule of the title compound, [Fe2(C15H19ClN3O)2O](CF3O3S)2·2C2H3N, is located on a crystallographic inversion centre and displays disorder in the coordinated methoxyethyl group. The counter-ion and the cocrystallized solvent molecule are also disordered over multiple positions. The five-membered chelate rings involving the pyridine N atoms are in an envelope conformation. The chelate ring involving the ether O atom is in a half-chair conformation in both disorder components.
