Crystal Structure of μ-Phenoxo-μ-benzoate-bridged Dinuclear Fe(II) Complex with a Dinucleating Ligand Having a Sterically Bulky Imidazolyl Group

Abstract

The structure of the dinuclear Fe(II) complex [Fe₂(Ph-bimp)(PhCO₂)(CH₃CN)](BF₄)₂·2CH₃CN·3CH₃CH₂OH (1) was determined by X-ray crystallography, where Ph-bimp is 2,6-bis[bis{2-(1-methyl-4,5-diphenylimidazolyl)methyl}aminomethyl]-4-methylpenolate. The compound crystallizes in a monoclinic space group Cc with a = 15.5690(10), b = 23.8260(8), c = 24.821(1)Å, β = 95.3460(3)°, Z = 4, V = 9167.2(10)ų. The R1 [I > 2σ(I)] and wR2 (all data) values are 0.0336 and 0.0850, respectively, for all 16812 independent reflections. The complex has a μ-phenoxo-μ-benzoate-bridged diiron(II) core structure.
