Nuclear magnetic resonance studies of Lewis acid-base interaction. I. Base adducts of Bis(ethylxanthato)nickel(II)

Abstract

The interaction between bis(ethylxanthato)nickel(11) and pyridine and 4-picoline in nitrobenzene was studied by N.M.R. spectroscopy at 34°C. The 1 : 2 equilibrium constants and proton n.m.r, isotropic contact shifts were obtained. The electron spin delocalization mechanism in the 1 : 2 adduct was discussed.
