摘　　要：A diorganotin（IV） complex [（CH3）2Sn]3L2（L=N＇-acetylsalicyl-hydrazide） 1 has been successfully synthesized and structurally characterized by elemental analysis,FT-IR,NMR（1H,13C and 119Sn） spectra and X-ray crystallography.The crystal structure belongs to an orthorhombic system,space group Pnma with a=8.5047（16）,b=28.466（5）,c=12.842（2） ,V=3109.1（10）3,C24H32N4O6Sn3,Mr=828.61,Dc=1.770 g/cm3,μ（Mo-Kα）=2.432 mm-1,Z=4,F（000）=1608,the final R=0.0378 and wR=0.0973 for 2125 observed reflections（Ⅰ 2σ（Ⅰ））.The complex is a trinuclear organotin（Ⅳ） containing five-and six-coordinated tin atoms.And weak but significant Sn···O intermolecular interactions lead to the assembly of complex into a 1D linear polymeric chain supramolecular framework.A diorganotin（IV） complex [（CH3）2Sn]3L2（L=N＇-acetylsalicyl-hydrazide） 1 has been successfully synthesized and structurally characterized by elemental analysis,FT-IR,NMR（1H,13C and 119Sn） spectra and X-ray crystallography.The crystal structure belongs to an orthorhombic system,space group Pnma with a=8.5047（16）,b=28.466（5）,c=12.842（2） ,V=3109.1（10）3,C24H32N4O6Sn3,Mr=828.61,Dc=1.770 g/cm3,μ（Mo-Kα）=2.432 mm-1,Z=4,F（000）=1608,the final R=0.0378 and wR=0.0973 for 2125 observed reflections（Ⅰ 2σ（Ⅰ））.The complex is a trinuclear organotin（Ⅳ） containing five-and six-coordinated tin atoms.And weak but significant Sn···O intermolecular interactions lead to the assembly of complex into a 1D linear polymeric chain supramolecular framework.
