A SnOW‐bound polyoxometalate : Targeted incorporation of {SnOMe} 3+ into lacunary {W 5 O 18 } 6− has been achieved by hydrolytic self‐assembly. The [(MeO)SnW 5 O 18 ] 3− ion undergoes a reversible one‐electron reduction, shows a large upfield shift of the W ax resonance in the 183 W NMR spectrum and has a calculated HOMO–LUMO gap of 3.5 eV. A wide range of {SnW 5 } derivatives is now accessible by ligand substitution at the Sn centre.
