In this work, for the first time, a compound based on the lacunar Keggin structure of polyoxometallate (POM) anion has been synthesized. Titanium and europium are the heteroatoms and lithium cations act as cations to the polyoxometallate ions. Elemental chemical analysis, synchronous thermal analysis and infrared spectroscopy were used to determine the qualitative and quantitative chemical composition of the compound and the structure of the polyoxometallate cluster. The presence of two types of weakly bound water molecules in the compound – crystalline and structural - as well as the lithium cation made it possible to obtain a liquid crystalline hydrate of the composition Li13[Eu(TiW11O39)2]*13H2O at room temperature. Low temperature calorimetric studies have shown that this compound is not crystalline, but turns into a glass state at temperatures below zero degrees centigrade (269 K). The resulting compound has a high ionic conductivity (210–4 Sim/cm). It also has a low activation energy of conductivity (0.145 eV). It is possible to relate the resulting compound to ionic liquids from the magnitude of the mobility of the lithium cations, determined by NMR relaxation methods. In addition, according to the CVA curve, the POM obtained not only has a sufficiently wide electrochemical window (about 1 V), but also good transparency in almost the entire visible range. It also has the ability to transform into a solid glassy state by losing water molecules in the air.
