The two symmetrical isomers in [Co(amp)2Cl2]2 (amp=2 (Aminomethyl)pyridine) system were synthesized by general oxidation method and were separated by chromatography and recrystallization method. Their configurations were assigned by using 2D NMR techniques, particularly the NOESY NMR spectra. Solvent used was Me2SO d6 with the central peak of the CD3 septet as the reference (13C,δ 39.37;1H,δ 2.49 relative to SiMe4). Cation exchange media used was Dowex 50Wx 2(H+ form, 200～400mesh; Biorad).
