新型含多铋(Ⅲ)配合物的合成与表征
　　Because of safety, no carcinogenic character and special bioactivities, the applications of bismuth complexes in many fields including medicine, materials, organic synthesis, and catalysis have been exploring increasingly. Synthesis of bismuth complexes has been studying interestedly. In this dissertation, synthesis and characterization of bismuth complexes Ring neodymium magnet with three class ligands were discussed.Firstly, polyaminopolycarboxylate ligands like nitrilotriacetic acid (H3nta), ethylenediminetetraacetic acid (H4edta), diethylenetriaminepentaacetic acid (H5dtpa), and 1, 2-Cylohexanediaminetetraacetic acid(H4cydta), bond to metal atom through N atoms and O atoms in varied chelate modes in different chemical condition Heterobinuclear complexes like BixLn1-xnta·nH2O (Ln = Nb, Eu, Y, Pr, x<1),hetero- bimetal bismuth complexes like [(NO3)Nd(H2O)4](μ3-cydta)[Bi(μ-O)NO2]·2.5H2O, [Mn(H2O)6][Bi(μ2-edta)]2·2H2O, LnBi(edta)](NO3)2·nH2O(Ln = La, Pr), and MBi(dtpa)·nH2O (M = Ba, Ca, Mn), were synthesized in water.Secondly, quinoline and 8-hydroxy-quinoline are of heterocyclic conjugate ligands containing N atom. Bismuth complexes with them have been synthesized in dilute HCl.Thirdly, nicotinic acid and 2-picolinic http://www.chinamagnets.biz/ acid are two special bioactive organic formal acids. Bismuth (Ⅲ) complexes with them have been obtained by different ways.Lastly, all of complexes synthesized were characterized by elemental analysis, FT-IR, and X single crystal diffraction or X powder diffraction. The cell parameters have been calculated by Rietveld program. The decompositions of complexes were studied by DTA or TG-DSC. Some physical characters were carried out.
