Abstract

Dinuclear Fe^III and Ni^II complexes, [(phenO)Fe(N₃)]₂(NO₃)₂ (1) and [(phenOH)Ni(N₃)₂]₂ (2), were prepared by treating Fe(NO₃)₃⋅9 H₂O and Ni(NO₃)₂⋅6 H₂O in methanol, respectively, with phenOH (=N-(2-pyridylmethyl)-N′-(2-hydroxyethyl)ethylenediamine) and NaN₃; both 1 and 2 were characterized by elemental analysis, IR spectroscopy, X-ray diffraction, and magnetic susceptibility measurements. Two ethoxo-bridged Fe^III and two azido-bridged Ni^II were observed in 1 and 2, respectively; corresponding antiferromagnetic interaction via the bridged ethoxo groups and strong ferromagnetic coupling via the bridged end-on azido ligands within the dimeric unit were observed. Complex 1 did not exhibit any catalytic activity, while 2 exhibited excellent catalytic activities for the epoxidation of aliphatic, aromatic, and terminal olefins.
