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[V6O17]·3H2O(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=1.6134(4)nm,b=0.8668(2)nm,c=1.3981(4)nm;β=103.070(4)°;V=1.9047(9)nm3;ρ=2.016 g/cm3;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[V6O17]·3H2O (1) (dien = diethylenetriamine), which was structur-ally characterized by elemental analysis, IR and single-crystal X-ray diffraction analysis. Results indi-cate that the product 1 belongs to monoclinic system of space group P2(1) /c, and its crystal data are determined to be a = 1.6134 ( 4 ) nm, b = 0.8668 ( 2 ) nm, c = 1. 3981 ( 4 ) nm, β =103.070(4)°, V = 1.9047(9) nm3,ρ = 2.016 g/cm3, 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}n helical chain.
