Synthesis, Structure, And Magnetic Properties Of Organic - Inorganic Hybrid Coordination Polymers Of The Type

Based on the investigations of a large number of literatures, We find that organic-inorganic hybrid coordination polymer compounds, which are vital varieties of material science, are fertile field and have attractive applied values. Upon that, this dissertation falls to doing works running after this hot point.The main contents of this dissertation are outlined as follows:(1) In simply explaining the magnetic spin coupling or magnetic exchange between the magnetic metallic ions, the dinuclear copper( ) complexes are very important. So we design and synthesize two dinuclear compounds ,one is oxpn-bridged compound:[Cu2(oxpn)L2](ClO4)2 {thereinto, oxpn is N,N -propylenediamide-bis(3-aminopropyl);L isl,10-N,N -fluorenone) ;the other is oxal-bridged compound: [Cu(tacn)]2(C2O-4)(ClO4)2 {thereinto, tacn is 1,4,7-triazacyclonane }.In addition ,we get two novel mononuclear copper( ) compounds : [Cu(tacn)](N3)2 and [Cu(tacn)2](ClO4)2.2H2O. Meanwhile, these complexes are characterized by IR, Elemental analysis, and their crystal structures are determined by X-ray diffraction. We foretell the magnetic properties of the dinuclear compounds by the ultraviolet spectrum in solid.(2) organic-inorganic hybrid derivatives of Prussian blue bycyanide-bridged ,which have good solubility and a variety of structures and can be reached the connection between the magnetic susceptibility and the structure. Herein, We prepared five novel coordination polymers, which can be obtained by assemlies from organic and inorganic molecular building blocks. These organic-inorganic hybrid coordination polymers were characterized by infrared spectrum, elemental analysis and their crystal structure were determined by single crystal X-ray analysis. We also study the magnetic susceptibility of two polymers, which show antiferromagnetism.
