| Abstract: | A square planar rhodium complex from the copolymer of 2-pyridyl ethylene and other low-molecular-weight rhodium complexes
with similar structure are reported. The experimental results of XPS and IR spectroscopy indicated that the weak N→Rh coordination
bond can easily replace the strong Rh-C back donation bond with the elevation of temperature due to the steric effect. The
terminal carbonyl group in the complex will be substituted to form tridentate and then tetradentate complexes. This is a reversible
process. When they are in the atmosphere of CO, tridentate and bidentate complexes will form. These experimental results provide
the theoretical reason why the catalytic activities from the polymer coordinated rhodium complex is superior to that of other
rhodium complexes.
