A Series of Molybdenum Halide Cluster Complexes with Acrylate and Metacrylate Ligands

Abstract We present the results of the synthesis and analysis of a series of organic-soluble cluster complexes of molybdenum: (Bu4N)2[Mo6X8L6] (X = Br, I; L = –CH2=CH–COO– (acrylate, Acr–) and –CH2=C(CH3)–COO– (metacrylate, MAcr–)). The complexes are obtained by interacting (Bu4N)2[Mo6X8X6] with silver salt of the respective acid. The mentioned compounds are characterized in detail by powder and single crystal X-ray diffraction, elemental analysis, IR and NMR spectroscopy. The luminescent properties and photophysical parameters of the solid cluster complexes are studied.
