Abstract
A heterodinuclear macrocyclic complex containing both Yb3+ and Na+ ions has been synthesized and characterized by X-ray crystallography and H-1 and Na -23 solution NMR; at room temperature the coordinated Na+ ion is in slow ch emical exchange with free Na+ ions and its NMR resonance is strongly shifte d.
