Syntheses, crystal structures and magnetic properties of two 1D copper complexes with Fe(IV) building block

Abstract

Two novel one-dimensional complexes [Cu(H2O)2Fe(L)]·2H2O·CH3OH (1) and [Cu(H2O)2Fe(L)]·1.5H2O (2) were synthesized with stable Fe(IV) building block and copper ions as starting materials. The structures of the two complexes were well characterized by single crystal X-ray diffraction, elemental analysis, IR spectroscopic and thermal analyses. Both complexes present of a different 1D chain structure in which the tetravalent iron block performed totally different coordination modes. Magnetic studies indicate that both complexes exhibit a typical antiferromagnetic behavior.
