| Popis: | The first liquid‐phase synthesis of high‐quality, small‐sized rare‐earth metal nanoparticles (1–3 nm)—ranging from lanthanum as one of the largest (187 pm) to scandium as the smallest (161 pm) rare‐earth metal—is shown. Size, oxidation state, and reactivity of the nanoparticles are examined (e.g., electron microscopy, electron spectroscopy, X‐ray absorption spectroscopy, selected reactions). Whereas the nanoparticles are highly reactive (e.g. in contact to air and water), they are chemically stable as THF suspensions and powders under inert conditions. The reactivity can be controlled to obtain inorganic and metal–organic compounds at room temperature. Reactive but easy to handle: For the first time, rare‐earth metals (La, Ce, Sm, Eu, Tm, Y, Sc) are obtained as high‐quality nanoparticles (1–3 nm in size) in the liquid phase. They can be highly interesting as reactive starting materials to realize new rare‐earth metal compounds and/or phase‐pure rare‐earth‐metal‐based materials. |
