NMR measurements carried out to study the coordination structure of lanthanide(III)-CMPO complexes indicate that the CMPO molecule is located in the equatorial region with respect to the principal magnetic Z axis. NMR longitudinal relaxation time measurements suggest that CMPO coordinates to the central Ce[sup 3+] ion in a bidentate manner with the phosphoryl and carbonyl groups. Further, it was observed that a rapid intramolecular interconversion occurs at a higher temperature region. 14 refs., 10 figs., 3 tabs.
