Cobalt-59 nuclear magnetic resonance study of some polynuclear cobalt(III) complexes

Abstract

The ⁵⁹Co n.m.r. spectra of 12 polynuclear cobalt(III) complexes are reported. Chemical shifts and linewidths are discussed in relation to the spectra of mononuclear species. Complexes containing chemically non-equivalent cobalt(III) atoms exhibit discernible resonances with differing chemical shifts. ⁵⁹Co N.m.r. spectroscopy is shown to be a useful tool in elucidating the structures of polynuclear cobalt(III) complexes.
