✦ Synopsis

Recently it has been shown [l] that 'H NMR spectra of both homo-and heterodinuclear paramagnetic metal complexes formed by the ligand 2pyridyl methyl ketazine (PMK) can be interpreted on the basis of a simple model. The isotropic shift AHi/H (MM') experienced by a ligand proton i in a given MM'(PMK):' complex can be considered as given by the sum of two contributions, one from the metal M which is closer to the given resonating proton, the other from the metal M' which is farther, according to the relationship
