Abstract
The difference of cobalt-59 chemical shift is much larger in ob-lel isomerism than that in mer-fac isomerism. The line widths of lel-isomers are 0.10 gauss and ob-isomers 0.14 gauss. The chemical shift values of four [Co(1-pn)3]3+ are as follows: Δ(mer), 938 ppm; Δ(fac), 951 ppm; Λ(mer), 863 ppm; and Λ(fac), 859 ppm upfield from external [Co(NH3)6]3+ standard.Keywords
