Synthesis and structural characterization of Tin (IV) Molybdotungstate-A Heteropolyacid Salt

The present study focused on the structure elucidation of a new heteropolyacid salt named Tin (IV) molybdotungstate, synthesized at pH 1.0 using sol-gel method. Instrumental techniques like XRD, IR, TGA, SEM and EDS were used to elaborate the structural aspects. XRD studies exhibited that prepared sample was having amorphous structure. Infrared spectroscopy was used to investigate the functional groups and the active sites supporting the acidic character and SEM and EDS techniques described the elemental composition of the synthesized sample. Thermogravimetric technique indicated the weight loss rate due to dehydration and helps in ascertaining the number of water molecules. The structure derived on the basis of above analytical techniques gave an impression of the polyoxometallates structure embracing various functional groups, water molecules, acidic nature and ion exchange characteristics. Thus, SnMoW can also be used in electro-analytical analysis
