Description
Pyridine N-Oxide and its monomethyl derivatives were found to form 1 : 2 adducts with bis (diethylthiophosphato) cobalt (II) complex, Co(DMP)_2 and electron spin density distribution in these ligands was studied by NMR. The unpaired electrons of cobalt atom were observed to transfer via π bonding from cobalt (II) to oxygen atom of amine N-oxides. Existence of some steric hindrance in α-picoline N-oxide adducts was estimated from the individual behaviros of β-protons of the amine. In addition to these results, NMR spectra of sulfur ligand protons of cobalt complexes were obtained only in pyridine-CDCl_3 solutions, and from the intensity of the absorption, the resonance protons were found to be methyl protons of ethyl groups in Co(DMP)_2.
