✦ Synopsis

A broad study of the 59C0 N M R of cobalt(1II) 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, 6, a d line width, ol/*, using the Kamlet-Taft equation. The dependence of 6 and olI2 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.
