Structure And Properties Of Ordered Metal Organic Complexes

Oxygen containing bidentate complexes can be used to be special catalytic,and with optical and magnetic properties,the synthesis of novel structure of oxygen containing bidentate complexes is becoming hot.Of these,especially the complexes containing zinc ions,nickel ions and other transition metal ions is one of the most important.Atmospheric heating method for complex crystal has the obvious superiority,this method can also achieve better reproducibility of experimental results than other methods,although it's experimental conditions for the less demanding circumstances,such as cheaper test instruments.Therefore,it's reasonable to choose the method of atmospheric heating.Using this method,A lot of new complexes was synthesized with value.This paper use isovanillin and ethyl vanillin as ligand,metal cations zinc ions and nickel ions as the center,95 percent ethanol and methanol as solvent,successfully synthetise two kind of oxygen containing bidentate complex.The first chapter,on the development of coordination compounds,the type and structure were summarized to determine the synthetic route in this paper complexes.Selection ethyl vanillin,succinic acid,benzimidazole and so easy to form a chelate ligand coordination bond,easily absorbed electrons reach 16 or 18 steady state electronic transition element zinc,cadmium cations as the coordination center.The second chapter,the synthesis of novel complexes of zinc ions and the formation of ethyl vanillin,from the perspective of start exploring the synthesis conditions,by changing different kinds of solvents and solvent ratio,adjust the pH of the reaction time of deployment three synthesized new ligands single crystal aggregates,with the X-ray single crystal diffraction,calculate the density of the single crystal structure was simple inference and parsing.The third chapter,stating the cadmium cation and an organic ligand succinic acid,benzimidazole,and inorganic ion complex ion Cl,The new complexes different octahedral shape is formed,cadmium complexes,the presence of carboxyl acid chelating oxygen atoms and center on the phenomenon of anions,enhance the stability of complexes.Room with ions formed by the polymerization of a long chain or mesh supramolecular aggregates.
