The iron(III) compound of composition [Fe(III)(salen)(2-Me-Him)]n, where H2salen = N, N′-ethylenebis(salicylaldimine) and 2-Me-Him = 2-methylimidazolate bridging ligand, was prepared. Magnetic resonance and magnetic susceptibility measurements showed the existence of linear and zigzag antiferromagnetic chains in the compound. Weak ferromagnetism was shown to arise in zigzag antiferromagnetic chains due to antisymmetric exchange interactions. The features of the temperature dependence of magnetization indicate that the magnetic system experiences the transition to the spin-glass state at a temperature below 30 K.
