Sodium Salts of Octahedral Molybdenum Complexes with Acrylate and Methacrylate Ligands

Abstract

Two new molybdenum cluster complexes Na₂[Mo₆I₈L₆] (L = –CH₂=CH–COO^– (acrylate, Acr^–) and –CH₂=C(CH₃)–COO^– (methacrylate, MAcr^–)) are prepared and studied. The complexes are prepared by solvothermal synthesis in methanol from Na₂[Mo₆I₈(OMe)₆] in the presence of small excess of the corresponding organic acid. As a result, XRD-quality single crystals of Na₂[Mo₆I₈L₆]·2MeOH are formed. The composition and purity of the phases are confirmed by the CHN elemental analysis, energy dispersion analysis, IR spectroscopy, and powder XRD. Photoluminescent properties of both complexes in the solid state and in a dimethylformamide solution are studied.
