Abstract

Pmr spectra of octahedral NiII, CoII, FeII complexes with pyridine-N-oxide and benzamide in solution with excess ligand have been recorded. The contact shift ratios of pyridine-N-oxide protons are identical for the three metals. Also the benzamide complexes, which reported to show different shift patterns for the three metals,1 are found to give rise to superimposable spectra of NiII and CoII and a stricly similar spectrum of FeII under excess ligand conditions. These data are interpreted as the experimental exidence of the validity of the ratio method.
