Abstract
We hereby report the synthesis, crystal structures and magnetic characterizations of three novel Cr(III) complexes: a mononuclear Cr(III)(HL((1)))₃ species along with two dinuclear μ-methoxo Cr(III)₂(μ-OMe)₂(HL)₄ (H₂L((1)): 2-salicyloylhydrazono-1,3-dithiolane; H₂L((2)): 2-salicyloylhydrazono-1,3-dithiane). EPR studies indicate that both dinuclear complexes (2a and 2b) are stable in solution (CHCl₃). Both Cr(III) dinuclear complexes exhibit a strong antiferromagnetic coupling. DFT calculations performed for complex 2a are in agreement with a strong antiferromagnetic exchange interaction in these new dinuclear Cr(III) complexes.
