The Study Of Synthetic Method For Functional Coordination Compounds

In this thesis, the influencesof synthetic method for the functional compound’s growth and structure is studied. The major research includes the induction of compound’s growth methods of disulfide bond formation reaction in dithiosalicylicacid, electrochemical method and the traditional hydrothermal synthesis method, etc.1.Compounds[Co(C10H8N2)2(H20)2]·2(C14H904S2)]n(1)and[Co(C10H8N2)2(H2O)2]·2(C12H7N2O4S2)]n(2) were synthesized by solution method with2-Mercaptonicotinic acid,2-mercaptobenzoic acid and4,4’-bipyridy, Results show that they have similar structure that is the three-dimensional networks structure which is constructed by C-H…π interaction.In addition both of the reactions have dithiosalicylicacid, that means the disulfide bond is built2. Based on the electrochemical principle, Compounds{[Cu2(pah)(Im)4(H2O)2]-DMF}n(3)and{[Cu2(pah)(Im)5(DMF)]-3H2O}n(4)(pah=1,2,4,5-tetra-carboxybenzene,Im=imidazole) were synthesized with1,1’-carbonyldiiazole,1,2,4,5-tetracarboxybenzene and Cu(Ⅱ).In complex(4), with copper plate as electrode, Cu(Ⅱ) are obtained by electrolytic through the electrochemical reaction,while in complex(3), Cu(Ⅱ) are added directly by copper salt. Under the same coordinated environment, the centre metal ion’s coordination mode is changed in the two complexes.3.Compounds [Ni4(pzdc)4(Im)4]·12H2O(5) and [Cu4(pzdc)4(Im)4]·12H2O(6)(pzdc=3,5-pyrazoledicarboxylic acid,Im=imidazole) were hydrothermally synthesized with Cu(Ⅱ)、Ni(Ⅱ) centre metal ion,3,5-pyrazoledicarboxylic acid and imidazole,they have similar tetranuclear structures.The3-D network structure in compound (5) is constructed by the interaction of the free water molecules between tetranuclear clusters. Water molecules are ordered arrange in complex (6).Compounds[Cu5(bpe)5(ma)10] n (7),[Cu(bpy)(ma)2]n(8),[Co(bpy)(ma)2]n(9)(bpe=1,2-bis (4-pyridyl)-ethane, bpy=4,4’-bipyridy, ma=formic acid) were also hydrothermally synthesized with dipyridyl-ligands(4,4’-bipyridy,1,2-bis (4-pyridyl)-ethane), formic acid which is decomposed by the solvent DMF and the centre metal ion Cu (Ⅱ)/Co (Ⅱ). The3-D network structure in compound(7) is constructed by the Intermolecular weak interaction. Both complexes (8) and (9) have regular polygon2-D network structure.
