An unprecedented octavanadium-substituted polyoxoniobate Na18[Nb48V8(OH)30O130]路33H2O (1), with a multiple-strand wheel structure, was successfully synthesized via a conventional aqueous method, which represents the largest vanadoniobate cluster reported to date. Single-crystal X-ray diffraction, ESI-MS spectrum, IR spectra, and UV鈥搗is spectra were investigated. In addition, photocatalytic H2 evolution activity for 1 under UV light was observed with TEA as a sacrificial electron donor.
