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.
Ammonium vanadate was used as a starting material to react with the first transition metal cation in divalent state at 160 ℃ in the presence of a chelating ligand to obtain a brown massive compound [Co (dien) _2 ] _2 [V_6O_ (17)] · 3H_2O (1) (dien = diethylenetriamine) were synthesized and characterized by elemental analysis, IR and single crystal X-ray diffraction.The results show that compound 1 belongs to monoclinic (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.Compound 1 is composed of vanadate and [Co (dien) _2] The oxygen layer is composed of {VO} n helical chains.
