Proton and Carbon-13 NMR Spectra of Paramagnetic Cobalt(II) Complexes containing Mono- and Di-methylpyridines

Abstract

¹ H and ¹³ C NMR spectra were obtained for a series of sixteen paramagnetic complexes of general formula [CoX ₂ LO ₂ ], where X is Cl or Br and L is a methylpyridine (picoline) or a dimethylpyridine (lutidine); use of inverse NMR and heteronuclear correlation 2D NMR spectroscopy allows full assignment of the carbon resonances for eight of them.
