合成了两个新的银(Ⅰ)配合物,[Ag2Br2(DPEphos)2(dppe)](1)和[Ag(DPEphos)(dppe)]NO3(2)(DPEphos=双[(2-二苯膦基)苯基]醚;dppe=1,2-双(二苯膦)乙烷),通过红外光谱、X-射线单晶衍射、核磁共振氢谱、磷谱和荧光光谱进行分析和表征。1是由Ag Br,DPEphos和dppe以2∶2∶1的比例混合反应得到的双核化合物,dppe通过2个P原子桥连2个Ag原子,而2是由Ag NO3,DPEphos和dppe以1∶1∶1的比例混合反应得到的简单的单核化合物,Ag原子与DPEphos和dppe配体螯合。在配合物2的膦谱中,存在4个分裂峰(双峰或者三重峰)。荧光光谱表明所有的发射峰均源于配体中的π-π*跃迁。
Two new silver (Ⅰ) complexes, [Ag2Br2 (DPEphos) 2 (dppe)] and [Ag (DPEphos) Phosphino) phenyl] ether; dppe = 1,2-bis (diphenylphosphino) ethane) was analyzed and characterized by infrared spectroscopy, X-ray single crystal diffraction, proton nuclear magnetic resonance, phosphorus and fluorescence spectroscopy. 1 is a dinuclear compound obtained by mixing Ag Br, DPEphos and dppe in a 2: 2: 1 ratio, dppe bridges 2 Ag atoms through 2 P atoms and 2 is a complex of Ag NO3, DPEphos and dppe at 1: The simple mononuclear compounds obtained by the mixed reaction of 1: 1 ratio, the Ag atoms chelated with DPEphos and dppe ligand. In the phosphine spectrum of complex 2, there are 4 split peaks (bimodal or triplet). Fluorescence spectra indicate that all the emission peaks originate from the π-π * transition in the ligand.
