Anion-selectivity of cationic cluster–organic nanospheres based on a nest-shaped [MS4Cu3X3] clustermonomer with a ditopic ligand

Three heterothiometallic cluster–organic nanospheres have been synthesized and characterized. They own identical cationic cluster–organic nanoball frameworks and show selectivity towards charge-balancing anions. It is also interesting that the morphology of the as-prepared particles can be tuned by simply varying the polarity of the solvent.
