在甲醇和二氯甲烷的混合溶液中合成了2个新的银(Ⅰ)配合物,[Ag2(dppp)2(phen)2](CF3SO3)2(1)和[Ag2(dppm)2(dpq)2](CF3SO32·3CH3OH (2)(dppp=1,2-双(二苯膦)丙烷,dppm=1,2-双(二苯膦)甲烷,phen=1,10-菲咯啉,dpq=[2,3-f]吡嗪并[1,10]菲咯啉),通过红外光谱、X射线单晶衍射、核磁共振氢谱、荧光光谱和太赫兹时域光谱进行了分析和表征.1是由AgCF3SO3,dppp和phen以1∶1∶1的比例混合得到的双核化合物.中心原子Ad(Ⅰ)通过双膦配体(dppp)桥联和含氮配体(phen)的螫合作用形成环.与1相似,2是由AgCF3SO3和dppm,dpq以1∶1∶1的比例反应得到的相似的双核化合物.荧光光谱表明所有的发射峰均源于配体中的π-π*跃迁.%Two novel silver (Ⅰ) complexes,[Ag2 (dppp)2 (phen)2] (CF3SO3)2 (1) and [Ag2 (dppm)2 (dpq)2] (CF3SO3)2 · 3CH3OH (2) (dppp=bis(diphenylphosphino)propane,dppm=bis(diphenylphosphino)methane,phen=1,10-phenanthroline,dpq=pyrazino [2,3-f][1,10]phenanthroline),have been synthesized in mixed solvent CH3OH and CH2Cl2 and characterized by IR,single-crystal X-ray diffraction,1H NMR spectroscopy,fluorescence spectra and THz time domain spectroscopy (THz-TDS).Complex 1 is of a binuclear complex,which was generated by the reaction of AgCF3SO3 and dppp with phen in 1∶1∶1 molar ratio.In complex 1,the central Ag(Ⅰ) ion forms a ring by the bridging bisphosphine ligand (dppp) and chelating N-donor ligand (phen).Like 1,2 is of a binuclear complex,which was obtained by the reaction of AgCF3SO3 and dppm with dpq in 1∶1∶1 molar ratio.The luminescent spectra show that all these emissions are assigned to ligand centered π-π* transition.
