The [Pd(dpa)(tsser)] complex ( 1) is prepared from the reaction of PdCl and 2,2′-dipyridylamine (dpa) with 4-toluenesulfonyl-L-serine (tsserH). This complex is characterized by spectral methods (IR, UV-Vis, H NMR, and luminescence), elemental analysis, thermal analysis (TG, DTA), and single crystal X-ray diffraction. X-ray structure determinations show that in this complex, Pd 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 tsser ligand.

[Ba(5,5´-dcbipy)(μ-H2O)2(H2O)2]n(1) complex was obtained from the reaction of one equivalent of 2,2'-bipyridine-5,5'-dicarboxylic acid (5,5´-dcbipy.H2) and one equivalent of ethylene diamine (en) with one equivalent of BaCl2.2H2O in water. This complex was characterized by elemental analysis, IR, UV-Vis, and luminescence spectroscopy and its structure was studied by the single-crystal X-ray diffraction method. The thermal stability of1was studied by thermogravimetric and differential thermal analyses. [ABSTRACT FROM AUTHOR]

[In(4,4′-dtbu-2,2′-bipy)Cl3(DMSO)].2DMSO (1) complex was obtained from the reaction of 1 equivalent of InCl3.4H2O with 1 equivalent of 4,4′-di-tert-butyl-2,2′-bipyridine (4,4′-dtbu-2,2′-bipy) in a methanol solution. This compound was recrystallized in a DMSO/methanol solution to obtain suitable crystals for X-ray studies. This complex was characterized by elemental analysis, IR, UV-Vis,1H NMR,13C{1H} NMR, and luminescence spectroscopy and its structure was studied by the single-crystal diffraction method. The thermal stability of 1 was studied by thermal gravimetric (TG) and differential thermal analyses (DTA). [ABSTRACT FROM PUBLISHER]
