Abstract: 
Five lanthanide trifluoromethyltricyanoborates [La{CF3B(CN)(3)}(3)(H2O)(4)]center dot 0.28H(2)O (2a), [Ln{CF3B(CN)(3)}(3)(H2O)(4)] (Ln = Eu (3a), Gd (4a)), [Ho{CF3B(CN)(3)}(H2O)(7)][CF3B(CN)(3)](2)center dot 1.23H(2)O (5a), and [Er{CF3B(CN)(3)}(H2O)(7)][CF3B(CN)(3)](2)center dot 1.34H(2)O (6a) have been synthesized in aqueous solution starting from LnCl(3).nH(2)O and (H3O)[CF3B(CN)(3)] and characterized by single-crystal X-ray diffraction. The coordination number of the Ln(3+) ions and the number of cyanoborate anions as well as the number of water molecules coordinated depend on the size of the Ln(3+) ion. All attempts to completely remove the water from 2a-6a resulted in decomposition. Surprisingly, the respective pentafluoroethyltricyanoborates are accessible as anhydrous compounds, for example [Gd{C2F5B(CN)(3)}(3)] (4b) that has been obtained from GdCl3 and (H3O)[C2F5B(CN)(3)] in water. In addition, the syntheses of the starting compounds (H3O)[(RB)-B-F(CN)(3)] (R-F = CF3, C2F5) and the crystal structure of (H3O) [CF3B(CN)(3)] are presented.
