Abstract
Three new hexanuclear Fe(III) coordination wheels [Fe6Cl6(L1)6]$5(MeCN) (1), [Na0.5Fe6Cl6(L1)6](N3)0.5$4.5(MeCN) (2), and [Fe6Cl6(L2)6]$2(MeCN) (3) have been synthesized with new prepared amino-acetonitrile derivatives 2-[bis(2-hydroxyethyl)amino]acetonitrile hydrochloride (H2L1) and 3-[bis(2-hydroxyethyl)amino]propanenitrile hydrochloride (H2L2). They were structurally characterized by single-crystal X-ray diffraction. M€oßbauer spectroscopy and magnetic susceptibility measurements indicate dominant antiferromagnetic behavior between the Fe(III) centers.
