Abstract

Treatment of the μ₃-oxo-centered mixed-valent trinuclear iron complex [Fe₃(μ₃-O)(μ-OAc)₆(H ₂O)₃] (1) in methanol solution with one, two, or three equivalents of 1-methyl-imidazole (C₄H₆N₂) afforded the substitution products [Fe₃(μ₃-O)(μ-OAc) ₆(H₂O)₂(C₄H₆N ₂)] (2), [Fe₃(μ₃-O)(μ-OAc) ₆(H₂O)(C₄H₆N₂) ₂] (3), and [Fe₃(μ₃-O)(μ-OAc) ₆(C₄H₆N₂)₃] (4), respectively. Complexes 2-4 were characterized by spectroscopic and elemental analyses, and the crystal structures of complexes 3 · 1.5MeOH · 2H₂O and 4 have been determined by single-crystal X-ray diffraction. The results indicate that in 2-4 the trinuclear core unit [Fe ₃(μ₃-O)(μ-OAc)₆] of 1 is preserved.
