ABSTRACT:
Novel lanthanide rare earth series cryptate coordination compounds or complexes are described. The compounds are highly kinetically inert in aqueous solution to dissociation of the complexes as a function of time. The compounds are particularly useful as relaxation agents in NMR spectra because of their stability in water or polar organic solvents and are also useful in electrochemistry, synthesis and medicine. A process for the preparation of metal cryptate coordination compounds in general is also described.
