Transmission of electronic effects in cobalt(III) complexes of macrocyclic ligands: 1H nuclear magnetic resonance study
Abstract
A correlation has been found between the chemical shifts of the methyl groups and the ligand field strength of X in the complexes [Co(MAC)X2]ClO4, where X = Br–, Cl–, N3–, NCO–, SCN–, AcO–, NO2–, and CN–, and MAC is one of four methyl substituted tetradentate macrocycles.
