  Synthesis, characterizations and crystal structures of di-n-butyltin(IV) complexes with heteroatomic (N, O or S) acid

  摘要：

  Two types of di-n-butyltin(IV) complexes {[(Bu2Sn)-Bu-n(O2CR)](2)O}(2) . L 1-4 and (Bu2Sn)-Bu-n(O2CR)(2)Y 5-8 (when L = H2O, R = 2-pyrazine 1; L = O, R = 2-pyrimidylthiomethylene 2, 1-naphthoxymethylene 3; L = C6H6, R = 2-naphthoxymethylene 4; when Y = H2O, R = 2-pyrazine 5; Y = O, R = 2-pyrimidylthiomethylene 6, 1-naphthoxymethylene 7, 2-naphthoxymethylene 8) have been prepared in 1: 1 or 1:2 molar ratios by reactions of di-n-butyltin oxide with the heteroatomic (N, O or S) carboxylic acids. The complexes 1-8 are characterized by elemental, IR, H-1 and C-13 NMR spectra. And except for complexes 6 and 7, the complexes 1-5 and 8 are also characterized by X-ray crystallography diffraction analyses, which reveal that the tin atom of complex 5 is seven-coordinated, while the complexes 1-4 and 8 are all hexa-coordinated. The nitrogen atom of the aromatic ring in complexes 1 and 5 participates in the interactions with the Sn atom. (C) 2004 Elsevier B.V. All rights reserved.
