Preparation of polyoxometalates in ionic liquids by ionothermal synthesis
TLDR
Ionothermal synthesis was applied to the formation of polyoxometalates (POMs) and two new compounds were successfully produced in the ionic liquid (IL) [EMIM]4Br.Abstract:
Ionothermal synthesis was applied to the formation of polyoxometalates (POMs) and two new compounds [EMIM]8Na9[WFe9(µ3-O)3(µ2-OH)6O4H2O(SiW9O34)3]·7H2O (1, [EMIM]8Na9[1a]·7H2O, EMIM = 1-ethyl-3-methylimidazolium) and [EMIM]4[SiMo12O40]·12H2O (2), have been successfully produced in the ionic liquid (IL) [EMIM]4Br. They were characterized by single-crystal X-ray diffraction, elemental analysis, UV-vis, IR and TG analysis. Furthermore, the magnetic properties of 1 and the electrochemical properties of 2 were studied. 1 is a high-nuclear transition metal substituted polyoxometalate (TMSP) and the unprecedented polyoxoanion of 1a is composed of three [α-SiW9O34]10− Keggin moieties connected by a {WFe9} cluster core. 2 is a heteropolyoxometalate with the polyoxoanion of α-Keggin type.read more
