| As a new type of functional materials,because of its rich topology structure,unique properties and potential application value of coordination compound,become a new hotspot in the research of the material chemistry field.In this paper,we have launched a series of work about the structure and properties research of Zn?,Cd?,Co?and Ni?metal complexes based on halogenated benzoic acid and N-containing ligands.Three series,a total of eight new coordination compounds have been synthesized base on hydrothermal synthesis technique and conventional solution methods.The structure of the compounds were analyzed by the related instrument.And their thermostability,and the photoluminescence of compounds have been preliminary dicussed.This paper roughly divided into five parts:In the first chapter,we introduce the development history and application value of coordination compound briefly.At the same time,we summarized the related results obtained in experimental research work.The second chapter,We had a summarization about the related experimental step involved in this article.The third chapter,four novel compounds based on 2-chlorobenzoic acid,1,1`-?1,4-butane?-bis?imidazole??bbi?or 1,1`-?1,4-dimethylene?-bis?imidazole??bix?,namely[Cd?bbi??ClC6H4COO-?2]n?1?,[Zn?bbi??ClC6H4COO-?2]?2?,[Zn?bix??ClC6H4COO-?2]?3?,and[Cd?bix??ClC6H4COO-?2]?4?were synthesized under hydrothermal reaction with Zn?and Cd? metal.In addition to the compound 1,the remaining three compounds are zero dimensional structure.Compound 1 is 2D supramolecular through the role of C-H...? and C-H...O.The other three compounds are 3D supramolecular.And the compound 2,3 and 4 is similar in structure.In the fourth chapter,two new compounds based on 4-bromobenzoic acid,and bbi,namely [Co?bbi??BrC6H4COO-?2]n?5?,and [Zn?bbi??BrC6H4COO-?2]n?6?,were synthesized under ?-? interactions with Co?and Zn?metal.Compound?5?is two-dimensional supermolecular network struture,the compound?6?is 3D supermolecular network struture.The fifth chapter,We have synthesized two novel compounds based on4,4`-?ethane-1,2-diyldioxy?-dibenzoic acid?H2eoba?,and 1,10-phenanthroline?phen?,namely[Co?eoba??phen??H2O?2]·2H2O?7?,and [Ni?eoba??phen??H2O?2]·2H2O?8?under hydrothermal reaction and ?-? interactions with Co?and Ni?metal.Compound 7 and 8 are isomorphic.The compound is 2D supramolecular structure through hydrogen bond.We further study their thermal stability.This paper discusses eight coordination polymer synthesis and the characteristics of the crystal structure,and its physical and chemical properties are detailed analyzed,for the reseach development of coordination polymer has accumulated valuable experimental data. |
