The 4-toluenesulfonyl-L-serine ligand (1), (tsserH(2)), was prepared from the reaction of L-serine and 4-toluenesulfonyl chloride in sodium hydroxide solution 1M. The complexes [Pd(4,4-dmbipy)(tsser)] (2) and [Pd(5,5-dmbipy)(tsser)].0.5CH(3)CN (3) (4,4-dmbipy is 4,4-dimethyl-2,2-bipyridine and 5,5-dmbipy is 5,5-dimethyl-2,2-bipyridine) were also prepared from the reaction of PdCl2 and 2,2-bipyridine derivatives with 4-toluenesulfonyl-L-serine ligand in mixture of CH3CN/CH3OH (3:1) and in presence of sodium hydroxide solution 0.5M. These compounds were characterized by elemental analysis, IR, H-1 NMR, and UV-Visspectroscopy and their structures were studied by single-crystal X-ray diffraction method. The X-ray structure determinations show that in the both complexes, the Pd-II atoms are four-coordinated in a distorted square-planar configuration by two N atoms from a bidentate bipyridine ligand and one N atom and one O atom from a bidentate tsser(2-) ligand.
