Abstract: A super molecular compound [HN(C2H5)3]2H[PW12O40]·4H2O has first been prepared by hy‐drothermal synthesis and characterized by elemental analysis ,IR and single crystal X -ray diffraction . Crystal data :triclinic ,space group C2/C ,a=2 .468 9(5) nm ,b=1 .0831(5)nm ,c=2 .248 2(5)nm ,α=90 .00° ,β=121 .094(5)° ,γ=90 .00° ,V=5 .148(3)nm3 ,Z=4 ,R1 =0 .045 6 ,wR2 =0 .1471 .The building block of the compound consists of two protonated triethylamine molecules ,four water molecules ,one pro‐ton and a Keggin‐type heteropolyanion of [PW12 O40 ]3 - .Different basic building subunits formed the 1D chainlike supramolecular architectures via hydrogen bonds .Then the 1D chains extended to 3D supramo‐lecular structure with the same weak interactions .
