Abstract
We have performed ab-initio calculations on 1:1 complexes of triglyme (triethylene glycol dimethyl ether) with different meter ions. Several stable tetradentate complexes have been found for each cation. The en ergy difference between the least stable and the most stable conformat ions ranges from 18 kJ/mole for the Na+ complex to 9 kJ/mole for the M g2+ complex. The considerable number of complexes obtained reflects th e great flexibility of the oligomer chain.
