• <SUP>13</SUP>C NMR relaxation times (<I>T</I><SUB>1s</SUB>) have been determined for monoazacrown ethers (<B>CA15C5</B> and <B>CA18C6</B>) and bis(monoazacrown ether)s (<B>BCA15C5</B>, <B>BCA18C6</B>, <B>BOA15C5</B>, and <B>BOA18C6</B>) in the absence and presence of Na<SUP>+</SUP>and K<SUP>+</SUP> ions. For the monoazacrown ethers with heptyl side chain and the bis(monoazacrown ether)s with pentamethylene bridge chain marked changes in <I>T</I><SUB>1</SUB> values are observed upon the complexation, and the changes are dependent on the cation and on the structure of the ligands. The complexation with Na<SUP>+</SUP> ion can give a larger effect on the <I>T</I><SUB>1</SUB> values for the bis(monoazacrown ether)s of 15- and 18-membered rings, especially on the mobility of the bridging chain carbons, which is indicative of the formation of an intramolecular sandwich complex. On the other hand, the present <I>T</I><SUB>1</SUB> study again shows the prominent effect of the oxygen in the bridging chain on the complexation of <B>BOA15C5</B> and <B>BOA18C6</B>. Small differences in <I>T</I><SUB>1</SUB> values obtained between Na<SUP>+</SUP> complexes and K<SUP>+</SUP> complexes of these two bis(crown ether)s suggest that the complexes take an analogous partial structure for the two cations.
