The structure of a 1,3-alternate-calix[4]arene·Na+ complex was determined by X-ray crystallography for the first time. It showed that two well-preorganized oxygen bases (OCH2CO groups) contribute to the Na+-binding whereas two π-basic benzene rings, unlike those for the K+ complex, are not involved. The complex adopts a highly symmetrical structure, which is the origin of the facile "Na+-tunneling" across the 1,3-alternate-calix[4]arene cavity.
