摘要：

The chiral compound (2-Me2NCH2C6H4) PhSbCl (1) was obtained from (2-Me2NCH2C6H4) Li and PhSbCl2 in 1 : 1 molar ratio, while (2-Me2NCH2C6H4) Mes(2)Sb (2) was prepared from (2-Me2NCH2C6H4) SbCl2 and MesMgBr in 1 : 2 molar ratio. The compounds 1 and 2 were used to obtain the Pd(II)/stibine complexes: [Me2NHCH2C6H5](+)[PdCl3{SbCl(Ph)(C6H4CH2NMe2-2)-Sb}](-) (3) and [PdCl2{SbMes(2)(C6H4CH2NMe2-2)N,Sb}] (4). All the compounds were characterized by multinuclear NMR spectroscopy in solution, elemental analysis, mass spectrometry and single-crystal X-ray diffraction studies. In compounds 1-3 the coordination geometry around the antimony atom is pseudo-trigonal bipyramidal, while in compound 4 a tetrahedral geometry around the antimony atom is observed. Theoretical calculations at the DFT level on compounds 1-4 were used in order to gain insight into the nature of the coordinative bonds.
