| In this paper,the perparation of the polyoxovanadate as the target, using ionicliquids as reaction solvent,solvent thermal bonding method instead of the conventionalhydrothermal synthesis method, by changing the reaction conditions, the way to controlthe feeding, adjusting the solution pH value, and use different types of ionic liquids assolvents, synthesized three no literature reports of the polymetallic oxygen sour saltcrystal, its chemical formula is determined by elemental analysis and TG analysis:[H2C10H8N2]2[H2P2Mo5O23]·H2O compound1[(C12H8N2)3Zn]2[PMoVI11MoVO40]·H2O compound2Cu2(C12H8N2)4Cl[PMo12O40]·H2O compound3Use of IR and X-ray single crystal diffraction, respectively for the structurecharacterization. Preliminary explored and discussed the factors influence the structureof the material.Structure analysis showed that Compound1has been hydrothermal synthesizedand structurally characterized. Compound1crystallizes in the triclinic space groupP2（1）/c with a=16.8010（7）, b=11.5299（5）, c=18.8847（7）,α=90,β=108.34,γ=90,V=3472.6（2）3,Z=4å'ŒGOF=1.235. Additionally, the IR, TG-DTA andSignal-crystal X-ray analysis of compound1were studied. We also studied theelectrochemical properties, electrocatalytic properties and the fluorescence of1.Compound2has been hydrothermal synthesized and structurally characterized.Compound2crystallizes in the triclinic space group P-1with a=12.1684（6）,b=13.8139（7）,c=14.7110（7）,α=105.369,β=91.439,γ=97.455,V=2359.6（2）3,Z=17å'ŒGOF=1.051. We also studied the electrochemical properties,electrocatalytic properties and the fluorescence of2.Compound3has been hydrothermal synthesized and structurally characterized.Compound3crystallizes in the triclinic space group P-1with a=12.5364（6）,b=13.4520（7）,c=21.2526（11）,α=9099.764（10）,β=94.141（10）,γ=95.107（10）,V=3504.1（3）3,Z=2å'ŒGOF=1.045.The compound is in ionic liquids in the synthesis of a new type of solid-state compounds, inorganic.
