Abstract

In order to extend existing ideas on isotropic spin transfer mechanisms in bipyridine-metal complexes, a series of unsymmetrical methyl-substituted bipyridine ligands, and their nickel (II) and cobalt (II) complexes, have been prepared, and their 1H nmr isotropic shifts measured experimentally. Simulating different electron spin density transfer mechanisms, from direct σ-electron density transfer to indirect π-mechanisms involving spin polarization ...
