摘要：

A new dimethyltin(IV) complex, {[Me2Sn(O2CNC9H6)](2)O}(2) (1), was prepared by reaction of dimethyltin(IV) dichloride with the quinoline-2-carboxylic acid and characterized by elemental analysis, IR, H-1-, C-13-, Sn-119-NMR spectroscopes. The structure of 1 was determined by single-crystal X-ray diffraction. The results showed that 1 is a tetranuclear, centrosymmetric dimeric, and contains two endo-cyclic five-coordinated and two exo-cyclic six-coordinated tin atoms and a N-atom of the 2-quinaldic carboxylate ligand coordinated to exo-cyclic tin. Complex 1 was utilized as a precursor for SnO2 nanoparticles by direct thermal decomposition at 500 A degrees C in air. The nano-structure of SnO2 was characterized by scanning electron microscopy and X-ray powder diffraction. The SnO2 core showed a band gap of similar to 4 eV determined from the UV/visible absorption spectrum. The SnO2 nanoparticles show stable photoluminescence (PL) with an emission centered at 557 nm.
