A broad study of the 59 Co NMR of cobalt(III) porphyrin complexes with axial amine ligands in a variety of solvents is reported. The data are presented in tabular form, as are the numerical correlations of chemical shift, δ, and line width, ω 1/2 , using the Kamlet‐Taft equation. The dependence of δ and ω 1/2 on ligand substituents is discussed. Solvent data, including mixed solvent results, indicate that general factors such as acidity, basicity, polarity and hydrogen‐bonding capability are important, as are the specific nature of the functional groups on the ligands and the solvent.
