Assembly of tetrameric dimethyltin-functionalized selenotungstates: from nanoclusters to one-dimensional chains†
Abstract
Two unprecedented tetrameric selenotungstates based on different Wells–Dawson-type fragments have been obtained: the {Sn7Se8W54} nanocluster exhibiting photocatalytic H2 evolution activity and the {Sn16Se11W56} chain, which are the first dimethyltin-functionalized selenotungstates reported and contain the unique {β-Se2W15} and {γ-Se2W14} building blocks, respectively.
