摘要：

The isotropic proton magnetic resonance shifts of the pyridine base adducts of bis(β-keto-esterato)nickel(II) complexes were measured. The slow exchange of γ-picoline was observed at room temperature. When a temperature was raised, the relative shift ratio among three signal of γ-picoline closely resembled to that in the case of bis(acetylacetonato)nickel(II) complex. With regard to the spin delocalization onto β-ketoesters, it was suggested by INDO calculations that ligand-to-metal β spin transfer was mainly responsible for it. © 1979.
