Synthesis And Studies Of Copper（Ⅰ） And Silver（Ⅰ） Complexes Supported By N/P Ligands （Dppm, PPh₃and Triazene）

In the past decades, particular attention has been devoted to the complexes of copper andsilver atoms with N-or P-containing ligands because of their potential aplications inbiochemical systems, industrial catalysts, magnetical and photoelectronic materials. Amongthem, Dppm、PPh₃and the triazenide groups had attracted our attention, as these compoundscould serve as a monodentate, a bidentate chelating and bridging ligands. So, synthesis ofnew complexes supported by P ligands and new triazene complexes and studying theirproperties and applications are of great importance to the development of coordinationchemistry.1、In this thesis, the reaction of AgNO₃、Dppm、PPh₃and TCNQ with a different molarratio produced two unprecedented silver compounds1[（PPh₃）₃Ag（-CN）Ag （PPh₃）₃] NO₃and2[Ag₃（dppm）₃（μ₃-Br）₂][DCTC]（DMF）. Their structures were also determined by X-raycrystallography. UV-Vis and IR spectra, the result that TCNQ turn out to be DCTC-.At theroom temperature they exhibited strong luminescence by solid-state emission spectra.2、This paper described the design and synthesis of two symmetrical triazenide ligands,1,3-bis（2-bromophenyl） triazene, referred to as HL1; and1,3-bis（2-chlorophenyl） triazenereferred to as HL₂. In the presence of Et3N, the reaction of the ligands with CuCl, CuBr andAgNO₃produces four new symmetrical binuclear complexes, which were characterized byUV-Vis spectra and emission spectra. Their structures have been determined by X-raycrystallography and1H NMR spectra.
