a series of lanthanide trifluoroacetic acid (H-TFA) derivatives which contain only the TFA and its conjugate acid has been developed. From the reaction of Ln(N(SiMe3)2)3 with an excess amount of H-TFA, the products were identified as: [Ln(μ-TFA)3(H-TFA)2]n (Ln = Y, Ce, Sm, Eu, Gd, Tb, Dy), [Ln(μ-TFA)3(μ-H-TFA)]n·solv (Ln·solv = Pr·2 H-TFA, H3O+, Ho·2py, Er·py, Yb·py, H-TFA), 3[H][(TFA)La(μ-TFA)3La(
摘要已开发出一系列仅含TFA及其共轭酸的镧系三氟乙酸(H-TFA)衍生物。根据Ln(N(SiMe3)2)3与过量的H-TFA的反应,产物鉴定为:[Ln(μ-TFA)3(H-TFA)2] n(Ln = Y,Ce ,Sm,Eu,Gd,Tb,Dy),[Ln(μ-TFA)3(μ-H-TFA)] n·solv(Ln·solv = Pr·2 H-TFA,H3O +,Ho·2py,Er ·py,Yb·py,H-TFA),3 [H] [(TFA)La(μ-TFA)3La(TFA)(μ-TFA)2(μc-TFA)2] n½(H2O)½( H2O,H-TFA)(La·½(H2O)1/2(H2O,H-TFA)),[(k2-TFA)Nd(μ-TFA)3] n·H-py +(Nd·H-py +), [(py)2Tm(μ-TFA)3] n(Tm)或[Lu(μ-TFA)4Lu(μ-TFA)3·H3O +] n(Lu·H3O
