The complexation behavior of nine polyether type podands with a varying number of oxygen donor atoms (4–10) towards the alkali metal cations Li+, Na+ and K+ was studied by quantum chemical methods at the DFT-B3LYP level of theory using the all-electron split-valence 6-311++G(d,p) basis set. The optimized structures of the complexes show a regular increase in the mean cation–oxygen distance with the...
