Abstract

original image

A SnOW-bound polyoxometalate: Targeted incorporation of {SnOMe}3+ into lacunary {W5O18}6− has been achieved by hydrolytic self-assembly. The [(MeO)SnW5O18]3− ion undergoes a reversible one-electron reduction, shows a large upfield shift of the Wax resonance in the 183W NMR spectrum and has a calculated HOMO–LUMO gap of 3.5 eV. A wide range of {SnW5} derivatives is now accessible by ligand substitution at the Sn centre.
