摘要：
Quantum chemical calculations of the [Mo3S7(Et2dtc)3](Et2dtc) complex in different solvents are performed. It is shown that the binding energy between the cluster [Mo3S7(Et2dtc)3]+ cation and the outersphere (Et2dtc)− anion exponentially decreases with increase in the solvent dielectric permittivity. By DOSY NMR it is determined that in chloroform, the cationic and anionic moieties of the complex form an associate (contact ion pair), while in strongly polar dimethyl sulfoxide these moieties move independently of one another.
