摘要：

Isotropic proton nuclear magnetic resonance shifts in pyridine adducts of nickel(II) complexes of β-thioketoesters were investigated. The paramagnetic mono-pyridine adducts which have different spin delocalization mechanism from paramagnetic di-pyridine adducts were detected when the pyridine-complex ratio was low. The five-coordinated complex was also detected by the spectrophotometric method. It was suggested that π delocalization mechanism plays a significant role for the delocalization of unpaired electron. © 1979.
