In order to assemble polynuclear iron(III) complexes, the coordination chemistry of the 2-hydroxyethyl-3,5-dimethylpyrazole (hedmp-H) ligand has been investigated. Reaction of hedmp-H with trinuclear iron carboxylate precursor [Fe3O(PhCOO)6(H2O)3]Cl in acetonitrile yielded the hexanuclear Fe(III) complex [Fe6O2(OH)2(PhCOO)10(hedmp)2]·3CH3CN (1). This aggregate has been characterized by employing various analytical techniques, spectroscopic studies and single crystal X-ray diffraction. Detailed magnetic susceptibility measurements revealed that 1 displays an ST = 5 ground state.
Graphical abstractA hexanuclear iron(III) complex, [Fe6O2(OH)2(PhCOO)10(hedmp)2]·3CH3CN featuring short Fe⋯Fe interaction is synthesized and characterized. Magnetic characterization reveal that this complex has a spin ground state of ST = 5 with a small magnetic anisotropy.Figure optionsDownload full-size imageDownload as PowerPoint slide
