The 18-crown-6-CCl4and the CCl4-CCl4pair potential functions were constructed from sets of interaction energies computed quantum mechanically at the HF/D95** and MP2/6-31G** levels. The simulation was carried out for a system consisting of 259 CCl4molecules plus one 18-crown-6 molecule. The simulation results reveal that there are two CCl4molecules in the first solvation shell; one lies above the ligand plane and other lies below it. The CCl4molecules prefer to approach closer to the O atoms than the C atoms of the 18-crown-6 molecule. The entire solvation structure around the 18-crown-6 was observed even the 18-crown-6-CCl4interaction is rather weak. © 2005 Elsevier B.V.
