Abstract
Sterically very hindered 2-methylbenzimidazole can bind high spin meso-tetraarylporphinatoiron(III) chloride to form a bis-ligated complex if the meso-aryl groups carry alkyl groups at 2,6-positions. The spin state and ligand orientation of this complex are discussed based on the NMR and EPR spectra.Keywords
