Magnetic resonance and structural investigations of (monooxooctaethylchlorinato)iron(III) chloride and its bis(imidazole) complex

X-ray crystallography and (super 1)H NMR spectroscopy are used to investigate (monooxooctaethylchlorinato)iron(III) chloride ((oxo-OEC)FeCl). The compound's bis(imidazole-d(sub 4)) complex is studied by multidimensional (super 1)H NMR and EPR spectroscopies, and the results are compared to those for the bis(Im-d(sub 4)) complex of (octaethylchlorinato)iron(III) chloride ((OEC)FeCl).
