“Molecular Symmetry Breakers” Generating Metal-Oxide-Based Nanoobject Fragments as Synthons for Complex Structures: [{Mo128Eu4O388H10(H2O)81}2]20, a Giant-Cluster Dimer

Abstract

Big rings and nanocleavage: Whereas a variety of molybdenum oxide based nanoobjects can be obtained by self-assembly concomitant with a variety of modifications of a parent cluster system under alterable boundary conditions, drastic changes—comparable to a molecular-scissors-type activity—can even cause splitting of the parent cluster to (large) fragments which subsequently can be linked in fascinating ways even with the option of generating giant cluster collectives (see picture {Mo}≡{MoO7(H2 O)}3−).
