摘要 通过三氟乙氧基钠盐和无水ErCl3以3∶1的摩尔比进行复分解反应,合成了多核烷氧基稀土簇合物[Er6(μ6-O)(OCH2CF3)18][Na(THF)3]2.PhMe,并测定了它的晶体结构:三角晶系,P-3空间群,a=17.879 6(11),b=17.879 6(11),c=12.581 4(11),V=3 483.2(4)3,Dc=1.858 g/cm3,Z=1,F(000)=1 900,T=193(2)K,λ(MoKα)=0.710 70. A Lanthanide - Sodium Trifluoroethoxide Clusters [ Er6 ( μ6 - O ) ( OCH2 CF3 ) 18 ] [ Na (THF) 3 ] 2 · PhMe was synthesized by the metathesis reaction of THF solution of NaOCH2CF3 with anhydrous ErCl3 in THF in 3:1 molar ratio. Its crystal structure was determined by X -ray diffraction. The crystallographic data: Trigonal, space group P -3, a = 17. 879 6( 11 ), b = 17. 879 6( 11 ), c = 12. 581 4 (11) A, V =3483.2(4)A3, Dc =1.858 g/cm^3, Z =1, F (000) =1 900, T =193(2) K, A (MoKα) =0. 710 70 A.
