文摘

Treatment of Na₂PdCl₄ with two equivalents of amino- or acetylamino-thiazoles [L = 2-aminobenzothiazole (abzt), 2-aminothiazole (atz), 2-acetylaminobenzothiazole (bzta) and 2-acetylaminothiazole (tza)] or 2-aminobenzimidazole (abzim)] affords trans-[PdCl₂L₂] complexes in which the introduced ligands are coordinated to palladium through the endocyclic nitrogen as shown by X-ray crystal structures of trans-[PdCl₂(abzt)₂]路dmf and trans-[PdCl₂(bzta)₂]路dmf. Addition of two equivalents of sodium saccharinate (Nasac) yields trans-[Pd(sac)₂L₂] complexes whereby the saccharinate anions are coordinated through nitrogen as shown by the X-ray crystal structure of trans-[Pd(sac)₂(abtz)₂]路2dmf. With thiosaccharin (Htsac) trans-[Pd(tsac)₂L₂] result but now the thiosaccharinate ligands coordinate through the sulfur of the thiolate group as evidenced by spectroscopic studies.
