Three new polyoxometalate-based hybrids prepared from choline chloride/urea deep eutectic mixture at room temperature

Three new polyoxometalate-based hybrids {[(CH3)3N(CH2)2OH]2(H3O)}[Na2(H2O)6][IMo6O24]·H2O 1 , {Na2[(CH3)3N(CH2)2OH]4}[Al(OH)6Mo6O18]2·8NH2CONH2·4H2O 2 and {Na6(H2O)18[(CH3)3N(CH2)2OH]2(CON2H5)2}[NaMo7O24]2·4NH2CONH2·H2O 3 were successfully synthesized in the choline chloride/urea deep eutectic mixture at room temperature. Reactant quantities of water presents in the nonaqueous eutectic mixture solvent may influence the structure of the products. The three compounds are fully characterized by elemental analyses, IR, UV–vis, TG analyses, power X-ray diffraction and single-crystal X-ray diffraction. The photocatalytic properties of 1 and 2 are investigated.
