complexes with water, dimethyl ether, and acetyl chloride. The energies of formation, the geometric parameters,
and the charge distributions of 2 : 1 molecular and 2 : 2 ionic complexes were calculated taking into account
the energy of solvation in a model solvent with
= 10. The formation of complexes with ion pair structures in medium-polarity solvents is shown to be thermodynamically favorable. According to calculation predictions,
the complexes should to a measurable extent dissociate to solvated ions under these conditions. The calculation
results are compared with available experimental data.
