摘要：

Compounds based on new cyanide cluster anions [{Mo6I8}(CN)(6)](2-), trans-[{Mo6I8}(CN)(4)(MeO)(2)](2-) and trans-[{W6I8}(CN)(2)(MeO)(4)](2-) were synthesized using mechanochemical or solvothermal synthesis. The crystal and electronic structures as well as spectroscopic properties of the anions were investigated. It was found that the new compounds exhibit red luminescence upon excitation by UV light in the solid state and solutions, as other cluster complexes based on {Mo6I8}(4+) and {W6I8}(4+) cores do. The compounds can be recrystallized from aqueous methanol solutions; besides this, it was shown using NMR and UV-Vis spectroscopy that anions did not undergo hydrolysis in the solutions for a long time. These facts indicate that hydrolytic stabilization of {Mo6I8} and {W6I8} cluster cores can be achieved by coordination of cyanide ligands.
