摘　　要：Antimony（III） complexes of thioamides [thioamides=thiourea （Tu）, N,N＇dimethylthiourea （Dmtu）, tetramethylthiourea （Tmtu）, imidazolidine-2-thione （Imt） and diazinane-2-thione （Diaz）] with the general formulae, Sb（thione）nCl3 （n= 1, 2, 2.5, 3） were prepared and characterized by elemental analysis, IR and NMR （1H, 13C） spectroscopic methods. The spectral data of the complexes are consistent with the coordination of the thiones to antimony（III）. The crystal structure of one of them, {[Sb（Imt）2Cl2]2（u2-Imt）}Cl2 （1）, was determined by X-ray crystallography, which shows that the complex is dinuclear consisting of two [Sb（Imt）2Cl2] units bridged by an Imt molecule. In 1, the antimony atom is bonded to two chlorine atoms, two sulfur atoms of coordinated Imt molecules and one sulfur atom of a bridging Imt molecule. The antimony environment can be considered to be distorted octahedral with one Cl- ion weakly bound to antimony.Antimony（III） complexes of thioamides [thioamides=thiourea （Tu）, N,N＇dimethylthiourea （Dmtu）, tetramethylthiourea （Tmtu）, imidazolidine-2-thione （Imt） and diazinane-2-thione （Diaz）] with the general formulae, Sb（thione）nCl3 （n= 1, 2, 2.5, 3） were prepared and characterized by elemental analysis, IR and NMR （1H, 13C） spectroscopic methods.
