Easily prepared and highly soluble actinide(III) salts are of great interest as precursors for actinide complex chemistry. In their Communication on page 6343 ff., P. Lindqvist-Reis and co-workers report how [An(H2O)9]3+(CF3SO3)3 (An=U–Cm, Cf) can be obtained directly from aqueous solution, a remarkable result for the UIII and NpIII salts given their extremely oxidation-sensitive nature. They also discuss the use of these salts as models for hydrated An3+ ions in solution.
