The synthesis of 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)...
The synthesis and characterization of the trifluoroacetic acid (H-TFA) derivatives of a series of alkaline earth congeners was undertaken through the dissolution of the alkaline earth (A E ) metal in H-TFA. After drying, the resulting reaction powders were independently crystallized from Lewis basic solvents [pyridine (py) or tetrahydrofuran (THF)] as diverse A E -TFA derivatives....
