Synthesis and spectroscopyic properites of novel polynuclear molybdenum(VI) peroxo complexes containing amino acids

摘要

The interactiono f an aqueous MoO_3 solution with H_2O_2, and glycine, serine, lysine, histidine or methionine, results in the precipitation of mononuclear MoO(O_2)_2LH_2O (L = glycine), dinuclear Mo_2O_4(O_2)_2L(H_2O)_4 (L = methionine, serine) and trinuclear Mo_3O_7(O_2)_2L(H_2O_6) (L =lysine,histidine) species. A detailed analysis of the electronic spectra has been performed using the digital filter method. It was found that the polynuclear complexes preserve the individuality of the molybdenum oxox peroxo core.
