摘要 Yb2O3与盐酸(1:1)按照物质的量为1:6混合成功的合成了化合物[YbCl5.6H2O]+[Cl]-,配合物通过了x-ray衍射表征。晶体结构表明,该配合物属于三斜晶系,其晶体呈双四角双锥结构,a=7.8331(11)A°,b=6.4632(9)A°,c=11.9589(12)A°,α=90deg,β=127.041(6)deg,γ=90 deg,V=483.27(11)A°3,Z=1,R[F2>2σ(F2)]=0.029,wR(F2)=0.067。此结构的测定有助于进一步研究稀土氯化物的反应性能。 The reaction of Yb2O3 with hydrochloric acid(1:1) by the ratio of 1:6 gives the title complex [YbCl2·6H2O]+-.The complex has been characterized by X-ray diffraction.The result shows that the crystal belongs to triclinic system and has double pyramid structure.a = 7.8331(11),b = 6.4632(9),c =11.9589(12),α = 90deg,β = 127.041(6)deg,γ =90 deg,V=483.27(11)3,Z= 1,R[F2 2σ(F2)] =0.029,wR(F2) =0.067.The result is helpful in further study of the reaction activity of lanthanide complex.
