level off at a mole ratio of 1:1 crown-to-metal indicating the formation of a stable 1:1 complexes. The order of the stability constants of the metalions studied with the Schiff base podands 14, 15 and 16 is: Hg2+ > Pb2+ > Cu2+ > Zn2+ > Cd2+ > Ag+. Metalion complexation by acyclic diamide or diester podands involves presumably the oxygen atoms of the carbonyl groups in addition to the nitrogen atoms
