Abstract

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]·dmf and trans-[PdCl2(bzta)2]·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]·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.
