An polyoxometalates (POMs)compound 3H3 [PMo12 O40 ]· 6MA· 31H2 O (1)(MA=Melamine)has been synthesized by solution evaporation method,which can trapped an infinite 2D water layers.X-ray single-crystal diffraction analysis revealed that the title compound crystallized in the trigonal system P-3 space group with a = 1.754 0(9)nm,b=1.754 0(9)nm,c= 1.330 5(3)nm,α = 90°,β = 90°,γ = 120°,V= 3.545 3(4)nm3 .The structure of the 2D-infi-nite water layers {(H2 O)30 }n was induced by the template effect of the Keggin-type POMs anion.The MA molecules fill-ing in the pores enhanced the stability of the water layers.Thermogravimetric,and electrochemical studies have been car-ried out.The results showed that title compound have good thermal stability and electrochemical properties.
