title: Linear Fe-C-O configuration in carbonyl 1-methylimidazole iron(II) porphyrin detected by XANES in dispersive mode.
abstract: The linear Fe-C-O configuration has been determined in the carbonyl 1-methylimidazole hindered iron(II) porphyrin derived from 'basket handle' complexes in which there are no constraints on the proximal imidazole. The structure at the iron site has been determined in toluene solution by fast measurements of XANES spectra, using the dispersive X-ray absorption method.
