- Chemistry of rare earth hypocoordinate oxocluster cations: Formation of novel oxoacetate clusters
-
A fast atom bombardment mass spectrometry (FAB MS) study of Ln(CH3COO)3·4H2O(Ln=Gd (1), Y (2)) was undertaken to explore the chemistry of hypocoordinate rare earth oxide cations (e.g. [LnO]+ and [Ln3O4]+), which are frequently encountered in FAB MS of rare earth compounds. A series of novel rare earth oxoacetate clusters, [LnxOy,(CH3COO)3x-(2y+1)] + (3) was readily and preferentially obtained over oxide clusters. Oxygenation is important for the stability of large clusters, i.e. 3, x≥4. Molecules or molecular ions such as [LnO]+,Ln2O3 and [Ln3O4]+ are coordinatively unsaturated, and may have a more extensive coordination chemistry.
