2016. 57, 3 - – - UDC 548.73:541.49:546.9 CRYSTAL STRUCTURE OF PALLADIUM(II) COMPLEX WITH 2,2-DIPYRIDYLAMINE AND 4-TOLUENESULFONYL-L-SERINE E. Mehdipour1, H. Bahrami1, S. Shamaei2, V. Amani3 1Department of Chemistry, Faculty of Science, Lorestan University, Khoramabad, Iran E-mail: e_mehdipour@yahoo.com 2Department of Chemistry,Faculty of Science, Khoramabad Branch, Islamic Azad University, Tehran, Iran 3Young Researchers and Elite Club,Yadegar-e-Imam Khomeini (RAH) Branch, Islamic Azad University, Tehran, Iran Received January, 12, 2015 The [Pd(dpa)(tsser)] complex (1) is prepared from the reaction of PdCl2 and 2,2-dipyridylamine (dpa) with 4-toluenesulfonyl-L-serine (tsserH2). <...> This complex is characterized by spectral methods (IR, UV-Vis, 1H NMR, and luminescence), elemental analysis, thermal analysis (TG, DTA), and single crystal X-ray diffraction. <...> X-ray structure determinations show that in this complex, PdII atoms are four-coordinated in a distorted square-planar configuration by two N atoms from a bidentate 2,2-dipyridylamine ligand and one N atom and one O atom from a bidentate tsser2– ligand. <...> Only eight palladium(II) mixed-ligand complexes with a formula of [Pd(L)(amino acid)] [ 18—23 ] have been synthesized and fully characterized by spectroscopic methods and their structures were studied by the single crystal X-ray diffraction method. <...> Furthermore, all of these palladium(II) mixed-ligand complexes have shown significant cytotoxic activity against several human tumor cell lines. <...> Thus, in the present paper, we report the synthesis, characterization, and crystal structure of a new palladium(II) mixed-ligand complex containing 2,2dipyridylamine and 4-toluenesulfonyl-L-serine. <...> Infrared spectra (4000—250 cm–1) of solid samples were taken as 1 % dispersion in CsI pellets using a Shimadzu-470 spectrometer. <...> UV-Vis spectra were recorded on a Shimadzu 2100 spectrometer using a 1 cm path length cell DMSO at room temperature. <...> Luminescence spectra were recorded on a Perkin Elmer LS 45 using a 1 cm path length cell. <...> Synthesis of 4-toluenesulfonyl-L-serine (tsserH2). 4-Toluenesulfonyl-L-amino acid was prepared according to the procedure previously described in [ 19 ]. <...> Softwares including Bruker APEX II (data collection and cell refinement) [ 31 ], Bruker <...>
