摘　　要：报道了一种新的杂多化合物[HN(C_2H_5)_3]_4-[Mo_3~VMo_6^(VI)V_7^(IV)O_(40)(PO_4)]·2[N(C_2H_5)_3]的合成,并用元素分析、EPR、IR谱、及X--射线单晶衍射等手段进行了表征。结果表明,该杂多酸盐属于单斜晶系,空间群P21/n,a=14.0841(3),b=14.2505(3),c=19.6089(3)?b=94.213(1),V=3925.0(1)?,Z=2,Dc=2.171g/cm3,Mr=2566.18,m=2.284mm-1,F(000)=2516,R=0.0477,wR=0.0945.杂多阴离子是1个16金属笼状物,笼中心包含1个PO4四面体客体。The novel molybdovanadophosphate [HN(C2H5)3]4[MoV3MoVI6VIV7O40(PO4)]2N(C2H5)3 was syn- thesized and characterized by elemental analysis, EPR, IR spectra and X-ray diffraction. The compound crystallizes in monoclinic, space group P21/n with a = 14.0841(3), b = 14.2505(3), c = 19.6089(3) ? b = 94.213(1), V = 3925.0(1) ?, Z = 2, Dc = 2.171 g/cm3, Mr = 2566.18, m = 2.284 mm-1, F(000) = 2516, R = 0.0477 and wR = 0.0945. The heteropolyanion has a novel hexadecametal cage [MoV3MoVI6VIV7O40(PO4)]4-which encloses a disorder PO43- guest.
