Assembly of high-nuclearity Sn₂₆ , Sn₃₄ -oxo clusters: solvent strategies and inorganic Sn incorporation.

ABSTRACT: A series of unprecedented high-nuclearity tin-oxo nanoclusters (up to Sn₃₄ ) with structural diversity have been obtained. The characteristics of the applied solvents had great influence on the assembly of these Sn-O clusters. Pure alcohol environments only gave rise to small clusters of Sn₆ , whilst the introduction of water significantly increased the nuclearity to Sn₂₆ , which greatly exceeds those of the known tin-oxo clusters (≤14); the use of aprotic CH₃CN finally produced the largest Sn₃₄ to date. Apart from the nuclearity breakthrough, the obtained tin-oxo clusters also present new structural types that are not found in previous reports, including a layered nanorod-like structure of Sn₂₆
