S. Attar et al., AXIAL LIGATION MODULATES THE ELECTRON-DISTRIBUTION IN HELICAL COBALT COMPLEXES DERIVED FROM OCTAETHYLBILINDIONE, Chemical communications, (12), 1997, pp. 1115-1116
Addition of pyridine to the four-coordinate cobalt(II) complex, [Co-II
(oebOx)]I-3, which shows an EPR spectrum with well resolved Co hyperfi
ne coupling, converts the complex into one with Co-III/ligand radical
structure and an EPR spectrum with g(z) = 1.98, and g(xy) = 2.02 and n
o cobalt hyperfine coupling.
