| Popis: | 89 This thesis is presented to investigate structural characterization and chemical properties of metal complexes which are composed of the N-phenyl-tripyridyltriamine ligand (H3ph-trptra) and transition metal ions. Mononuclear, octahedral transition metal complexes, [ML2]n+, containing the neutral tridentate H3ph-trptra ligand and a MnⅡ, FeⅡ, CoⅡ, NiⅡ, ZnⅡ, RuⅡor RhⅢ ion have been synthesized. All of the [M(H3ph-trptra)2]2+ ( M = CoⅡ, NiⅡ, ZnⅡ, RuⅡ) complexes reveal a distorted octahedral conformation with two tridentate meridionally coordinated H3ph-trptra ligands wrapped around the metal center in an all-anti conformation. The complexes [M(H3ph-trptra)X]n+ ( M = CuⅡ, X = CH3CN；M = PdⅡ, X = Cl ) reveal a distorted square planar conformation with a tridentate H3ph-trptra ligand coordinated to the metal ion in an all-anti conformation. According to the results of magnetic measurement, the electronic configurations of the central metal ions of mononuclear transition metal complexes ( MnⅡ, FeⅡ, CoⅡ, NiⅡ, CuⅡ) are paramagnetic. In related word, we are trying to synthesize multinuclear metal string complexes, and the complex [Ni5(m5-Hph-trptra)4Cl2] has been successfully synthesized and primitively characterized by FAB-mass spectrum. |
