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