摘要

A new inorganic–organic hybrid 4-Ti-added polyoxometalate: [H₂N(CH₃)₂]₂Na₃H₅[{Ti(C₂O₄)(H₂O)}₂{Ti(C₂O₄)}₂(B-β-SbW₉O₃₃)₂]·22H₂O (1) has been successfully made and further characterized by infrared spectroscopy, thermogravimetric analysis, powder X-ray diffraction and single-crystal X-ray diffraction. The polyoxoanion of 1 exhibits a Krebs-type structure that is constructed from two [B-β-SbW₉O₃₃]⁹⁻ fragments fused together by a belt of four additional Ti atoms decorated by oxalate ligands. Furthermore, 1 as a heterogeneous catalyst exhibits high activity for Knoevenagel condensation under mild reaction conditions.
