    • 2 to a lower field upon coordination to a transition metal. Values in a range of 150-250 ppm have been reported, and the chemical shifts may differ widely even for complexes with the same coordination mode. A concerted rotation of the two carbon dioxide ligands, in which both molecules rotate in the same direction, has been demonstrated by variable-temperature NMR spectroscopy.
