Abstract

Three novel trinuclear mixed-transition-metal complexes of Fe(III), Co(III, II), Ni(II) and Cr(III)), with pyridine-2-amidoxime (Hpa) ligand are synthesized, i.e. [FeNi2(pa)6]Cl·15H2O (1), [CrNi2(pa)6]OH·5H2O (2), and [CoCo2(pa)6]NO3 (3). These complexes are characterized by variable-temperature magnetic susceptibility, electrochemistry, and single crystal X-ray diffraction methods. 1 and 2 are heteronuclear metal clusters in the perfect linear arrangement, i.e. [NiII⋯FeIII⋯NiII and [NiII⋯CrIII⋯NiII] respectively, while 3 is linear [CoII⋯CoIII⋯CoII] trinuclear. Theoretical calculations are employed to successfully account for the experimental results of the variable temperature magnetic susceptibility.
