%X Complexes of Na+ and K+ ions with dibenzo-18-crown-6 (6,7,9,10,17,18,20,21-octahydro-dibenzo[ b,k ] [1,4,7,10,13,16] hexaoxacyclooctadecin ) were studied by polarography in several non-proton-donating media. Their stability constants are strongly influenced by the solvents, and vary inversely with the Gutmann donicity scale and with the Persson HDS parameter which is a measure of the hardness for these solvents.
