【Abstract】 A super molecular compound[HN(C2H5)3]2H[PW12O40]·4H2O has first been prepared by hydrothermal 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 proton and a Keggin-type heteropolyanion of[PW12O40]3-.Different basic building subunits formed the 1D chainlike supramolecular architectures via hydrogen bonds.Then the 1Dchains extended to 3Dsupramolecular structure with the same weak interactions.更多还原
