Abstract

A neoteric hepta-nuclear Ti-oxo-cluster-substituted tetrameric tungstoantimonate [H ₂ N(CH ₃ ) ₂ ] ₂₂ Na ₁₈ {Ti ₇ O ₆ (SbW ₉ O ₃₃ ) ₄ } ₂ ·124H ₂ O (1) has hydrothermally been synthesized and tested by single-crystal/powder X-ray diffraction, IR spectra, and thermal analysis. The glamorous feature of this tetrameric polyoxoanion is an uncommon hepta-nuclear Ti-oxo-cluster octahedron [Ti ₇ O ₆ ] ¹⁶⁺ enclosed in four [B-α-SbW ₉ O ₃₃ ] ^9- building units. As a heterogeneous catalyst, the investigation on catalytic oxidation with H ₂ O ₂ for multiple thioethers indicated that 1 possesses high conversion and remarkable selectivity. Additionally, 1 exhibits good stability and excellent recyclability.
