摘要 由N-甲基吡咯烷酮和H3PW12O40.nH2O反应得到了标题化合物,并以元素分析,红外光谱,质谱和X射线单晶衍射对其结构进行了表征.结构解析表明,该化合物属于三斜晶系,P墿空间群,晶胞参数为:a=1.335(2)nm,b=1.374(2)nm,c=1.826(2)nm,α=98.92(2)°,β=107.7(2)°,γ=109.9(2)°,V=2.873(1)nm3,Z=2,Dc=3.840 Mg/m3,μ=24.05 mm-1,F(000)=2 926,R1=0.063 2,wR2=0.140 3.在该化合物中,杂多阴离子仍保持其Keggin结构,通过静电引力与阳离子作用. The title compound was synthesized using N-methylpyrrolindone and H3PW12O40·nH2O as starting materials, and identified by elemental analyses, IR spectra, MS and single crystal X-ray dif- fractometry. The crystal belongs to triclinic, space group Pi, with a = 1. 335(2) nm, b = 1. 374(2) nm, c=1.826(2) nm, α = 98. 92( 2)°, β=107.7(2)°, γ=109.9(2)°,V= 2.873(1) nm^3, X=2, Dc =3.840 Mg/m^3, μ =24.05 mm^-1, F(000) =2 926, R1 =0. 063 2, wR2 =0. 140 3. In the title compound, the heteropoly anions still reserve their Keggin structures, which combines the cations through static electric force.
