Abstract

This work reports a synthesis and crystal structures of [Mo6I8(DMSO)6][PM12O40](NO3) (M = Mo, W) double complex salts. The compounds are prepared by a reaction between the [Mo6I8(DMSO)6]4+ cationic cluster and [PM12O40]3– anionic polyoxometalates (POMs) in the 1:1 molar ratio. The luminescence quenching of the cluster complex in the presence of polyoxometalates is studied. It is shown that none of the compounds exhibits luminescent properties, thus indicating the possibility of electron/energy transfer from the excited state of the cluster complex to the polyoxometalate. The obtained results are an important step in the development of new functional materials based on hybrid cluster–POM systems.
