The coordination reaction of 2, 3-benzo-8,11,15-trimethyl-18-crown-6 (BC3-18C6) with alkali metal ions (Na~+, K~+ and Cs~+)in aqueous solution was discussed theoretically by CNDO/2 method. The calculated sequence of stability of the coordination compounds formed between the BC3-18C6 and the alkali metal ions (Na~+, K~+ and Cs~+) in aqueous solution was as follows: K~+>Na~+>Cs~+ It was in agreement with that obtained by calorimetrio titration method.The calculated results of coordination and hydration energy showed that the hydrated alkali metal ions could coordinate with crown ether, increasing the stability of the coordination compounds, and two molecules of water occupied the axial positions of metal ions as ligand.It was also found that the metal-oxygen bonds formed between alkali metal ions and oxygen atoms of ether were weaker than those of hydrated alkali metal ions. So, it is concluded that both macrocyclic and solvation effects played important roles in stabilizing the coordination compounds.
