Abstract:
A building blocks strategy is an effective approach for constructing the large molecular systems. Herein, we demonstrate that high‐resolution electro‐spray ionization mass spectrometry (HRESI‐MS) provides an effective chance to insight the assemble process of the building blocks and guides the construction of high‐nuclearity metal clusters on the basis of the reaction of Ti(O i Pr) 4 , Eu(acac) 3 , and salicylic acid. The time‐dependent HRESI‐MS indicates that not only a Eu 3 Ti building block can be formed, but that it can further assemble into a Eu 24 Ti 8 compound. Temperature‐dependent HRESI‐MS reveals that increase of the reaction temperature favors the formation and crystallization of the stable Eu 24 Ti 8 structure. Single‐crystal structural analysis demonstrates that the Eu 24 Ti 8 has a wheel‐like structure with diameter of ca. 4.1 nm and is the highest nuclearity lanthanide‐titanium oxo cluster reported to date.
