摘　　要：以钒酸铵为起始原料,在螯合配体存在下,利用水热合成法将其与二价第一行过渡金属阳离子在160℃反应得到了一个棕色块状化合物[Co(dien)_2]_2[V_6O_(17)]·3H_2O(1)(dien=二乙烯三胺),并用元素分析、红外光谱和X射线单晶衍射对之进行了定性分析.结果表明,化合物1属于单斜晶系,P2(1)/c空间群;其晶格参数为:a=1.613 4(4)nm,b=0.866 8(2)nm,c=1.398 1(4)nm;β=103.070(4)°;V=1.904 7(9)nm^3;ρ=2.016 g/cm^3;Z=2.化合物1是由钒氧层和[Co(dien)_2]^(2+)构成.这些钒氧层是由{VO}n螺旋链组成.The hydrothermal reaction of ammonium vanadate as starting materials with divalent first-row transition metal cations in the presence of nitrogen donor chelating ligands at 160 ℃ yielded the brown block solid of [Co(dien)_2]_2[V_6O_(17)]·3H_2O(1)(dien = diethylenetriamine),which was structurally characterized by elemental analysis,IR and single-crystal X-ray diffraction analysis. Results indicate that the product 1 belongs to monoclinic system of space group P2(1)/c,and its crystal data are determined to be a = 1.613 4(4) nm,b = 0.866 8(2) nm,c = 1. 398 1(4) nm,β =103.070(4) °,V = 1.904 7(9) nm^3,ρ = 2.016 g/cm^3,Z = 2. The crystal structure is composed of vanadium oxide layers and [Co(dien)_2]^(2+) fragments. These vanadium oxide layers are composed of a{ VO}nhelical chain.
